Tebongkar! Rahasia Cepat Memahami Kinematika Gerak dengan jelas dan detail! (Seri Fisika Dasar)

Brief Summary

This video provides an introduction to kinematics, a branch of physics that studies the motion of objects without considering the causes of that motion. It covers one-dimensional and two-dimensional motion, including uniform straight motion (GLB), uniformly accelerated straight motion (GLBB), free fall, vertical motion, circular motion, parabolic motion, and relative motion. The video also presents key formulas used in kinematics and discusses the conditions under which they apply.

  • Kinematics studies motion without considering its causes.

Introduction to Kinematics

The video introduces kinematics as the study of motion, distinguishing it from dynamics, which considers the causes of motion. Kinematics focuses on describing how objects move, covering various types of movements without delving into the forces or reasons behind them. The discussion is limited to Newtonian mechanics.

One-Dimensional Motion

One-dimensional motion involves movement along a single axis, such as the x-axis. Examples include a car on a straight road or a train on its rails. In this type of motion, the direction remains constant. Uniform Straight Motion (GLB) is discussed, where the speed is constant. The formula for distance traveled in GLB is speed multiplied by time (s = v*t).

Uniformly Accelerated Straight Motion (GLBB)

GLBB involves motion along a straight line with constant acceleration. In this case, the velocity changes uniformly over time. Three common formulas for GLBB are presented, which are applicable when acceleration is constant. These formulas relate displacement, initial velocity, final velocity, acceleration, and time.

Vertical Motion

Vertical motion is influenced by gravity. Free fall is a type of vertical motion where an object falls without any initial velocity. Vertical motion can also involve an object being thrown upwards with an initial velocity. The plus or minus signs in the equations depend on the direction of motion.

Two-Dimensional Motion

Two-dimensional motion involves movement in both the x and y axes. Circular motion, where an object moves along a circular path, is one example. In uniform circular motion, the angular velocity (omega) is constant. Parabolic motion is another type of two-dimensional motion, where the object follows a parabolic trajectory, such as a football during a free kick.

Relative Motion

Relative motion involves the motion of an object as observed from a particular frame of reference. The focus is on relative speed or relative acceleration between two observers. This is different from relativity, which deals with very high speeds approaching the speed of light. The discussion is generally limited to constant acceleration scenarios.

0:00 Indonesia house Hello welcome back to the physics.com channel with friends using and like this, my brother wants to share Sharing about soto concept which is usually This concept lives first appears in entering the door of physics okay well this is none other than about kinematics Okay what is kinematics that in Newtonian mechanics we learn it usually Teduh is about kinematics and dynamics Well now

0:48 focus on kinematics is one root word from the word cinema cinema Okay so we turn this off we will learn about our movements meaning learning about a movement various kinds of movements which immediately now the cause is unknown Meaning we don't need to know what the cause is Well this is our post if the cause is known later the name is by running away but for now let's just focus on kinematics okay what is studied this movement is

1:36 usually generally studied Only two okay first Hi Graha there is a y axis x one dimension often this Queen is the blonde study the second is two-dimensional motion [Music] Indonesia okay okay approximately 1 dimension is dimension well there is one like this two dimensions three dimensions like that So

2:22 if one dimension only still separate the movement too X moves along x-axis I walk forward and backward that's appropriate or a car is walking on a motorized highway on the road like that the train moves on its rails that usually happens in that phenomenon ideals heal yes distance to the x-axis

3:10 and direction remains dawn buyek usually rarely there are also edges that walk this Hi now atos2 learn what should Later the phenomenon that often occurs hopefully not directly X usually the movement from extraordinary that happens that usually can happen GLBB uniform straight motion Well after months of changing poison Okay maybe it's

4:05 clear straight so no turns uniform straight motion well what is regular means regular means fixed arrangement or other terms Hotel understand who here is constant the one that remains the rule is Speed ​​is fast speed can also be hot speed What is speed will be discussed in separate video material to focus on now I'm more contact

4:53 for what materials are in the word of God later the speed is so he has no change in constant speed so for the speed and distance traveled is speed times time yes yes okay okay understand yes come here Why do n't you understand that straight motion changes regularly Okay we call

5:40 the movement straight straight continues to change what is below Well which apparently is the speed so the TV is changing eventually no no Okay the TV changes it continues to be regular earlier other terms battery here constant remains constant Okay is constant or nothing else is not the same as please you stay in the

6:29 speed especially here if there is no acceleration is constant remains so whatever is not taken constant acceleration in the form of the second speed changes speed changes also this is usually generally not studied in high school or college complete basic in basic physics usually not too free you discuss it later to you guys continue for example majoring in Physics like my GPS numbers are increased later compared to fish can just learn about acceleration that is not okay okay

7:14 enough up to here so in this kinematics chapter in general we discuss constant acceleration there is no there are three formulas that are very easy to memorize or very well known by children or students who In the past when I was in junior high school in 2012 on TV on the channel tea was busy plus

8:02 two Alphard X today at certain times certain times feat not Well later here maybe will specifically make a video explaining about the proof or emergence of this time enough this applies if if constant So

8:47 if there is one that is not too okay you will definitely understand okay Well, if it's like this, does it happen big? Well, if it's true, it turns out that only one thing can be what is it because if we have vertical movement, usually there is a factor that always influences the movement. What is that factor, namely the existence of a before I, so

9:33 in vertical motion, Impossible, it is impossible for a movement to have a constant speed. Okay, usually this is studied, the first movement is the only movement, namely more, that is free gay I fall freely, free fall movement, the movement that falls down, falls and is free, free means free, it is not in the free market,

10:18 free, for example, this video, free fall movement is free, but the movement is free, it is not influenced by the initial speed for any group, it is vertical motion. Hi, up, overflowing, up. Hi, the captain is involved above, well, this is influenced by a pull or push or a big throw, so there is a person's speed, so I throw this up with the initial speed,

11:08 vertical movement down, until it reaches the bottom, the difference is calling the old man and Oh, this is not voluntary, it will be installed down, but Well, come here, you will definitely understand what it means for the plus minus sign, later I will explain the special theme about the uniform straight motion fgbb, for now, the second one is enough,

11:55 so the movement is other than against The x-axis also changes or moves in the direction of the y-axis when the movement is two- dimensional, so no, Hi, circular circular motion, this circular motion can happen like Hi, okay, regular circular motion from their

12:45 movements, those are my rules. What are other terms, constant or constant, here Omega, constant angular velocity or constant even if there is an effect on acceleration. Okay, straight. This condition is like

13:35 this, seeing you Shinigami, initially a second here, then after a few seconds he arrived here, well, what he achieved is the angle with Well, that has exceeded this, the length of this path. Hi, gadget. So, for example, if he moves one full rotation, one full rotation, one circle is not

14:31 constant or not. Later, okay, okay, okay, negative, next, not two-dimensional, we learn more about parabolic motion.

15:21 Why is it possible that the movement is said so that the parabola turns out to be bad, so he can mix it up. So, besides telling the x-axis, the y-axis, let's Hi, everyone, it takes too long, even for example, in football, there are free kicks. Well, it's too mosque, don't just ignore it. But he's above it, so there's above. My version of the balloon also continues, the

16:15 second one doesn't, so if the speed changes, the straight motion changes, it changes, it's not counted, actually wondering G victim here okay one more thing usually this movement is usually studied in basic physics for example in grade 1 at tpb IPB my

17:02 basic physics course Okay usually relative motion Hi more notes Black motif here is not relative motion which is like relativity it is not not activity eating both there are two observers it is relative but you relativity the speed is very large very fast approaching light that this but if here here what is emphasized is not more to but more speed question about relative speed Hi or relative acceleration

17:50 Kyuhyun okay so until again usually in general divided kinematics discusses it is about constant acceleration moreover the formula this video continues to play a constant role okay indeed it can not also change that time the time continues to increase meaning only that Okay Okay so if the case is like this This formula does not apply which is generally studied in high school

18:37 or basic physics 1 students can learn about what is said hi okay maybe about the introduction of kinematics in general which will be studied like this hopefully this material is useful for friends for all of you if you feel this channel is useful please continue to support Sis by subscribing share or Comment is in the status of this series, this channel will be enough. That's all for this discussion. Thank you for

19:26 your attention, see you on another occasion and stay optimistic, greetings from physics and whisper the lounge like
