The course on motion in one dimension have been designed for students who want to build a better understanding of this topic .
The course have been designed for students aged between 10 to 15 years or those students who want to develop understanding on the concept of kinematics without using calculus and vectors.
In everyday life , we see some objects at rest and others in motion . Birds fly , fish swim , blood flows through veins and arteries and car moves.Atoms , molecules ,planets ,stars and galaxies are all in motion. We often perceive an object to be in motion when it changes its position with time . However there are situations where the motion is inferred through indirect evidence s. For example we infer the motion of air by observing the movement of dust and leaves .
What causes the phenomenon of sunrise , sunset and changing of season? Is it true to the motion of earth ? If it is true why dont we directly perceive the motion of earth?
An object may appear to be moving for one person and stationary for some other. For the passengers in a moving bus , the roadside trees appear to be moving backwards. A person standing on the roadside perceives the bus alongwith the passengers as moving. However a passenger inside the bus sees his fellow passengers to be at rest . What do these observations indicate?
Most motion are complex. Some objects may move in a straight line, others may take a circular path. Some may rotate while others may vibrate.
In this course we will first learn to describe the motion along a straight line . We shall also learn to express such motions through simple equations and graphs. Later we will discuss ways of describing circular motion.
The content of this course covers following topics in depth .
Motion in one dimension - Motion is described in terms of displacement (x), time (t), velocity (v), and acceleration (a). Velocity is the rate of change of displacement and the acceleration is the rate of change of velocity.
You will learn the following: 1) Distance and Displacement
2) Speed and Velocity
(3) Average speed and average velocity
(4) tricks to solve numericals based on average speed and average velocity quickly
(5) Uniform and Non-Uniform Motion along a straight line
(6) Acceleration concepts
(7) Numericlas based on acceration
(8) Complete understanding of Distance-Time and Velocity-Time graph for uniform motion and uniformly accelerated motion.
(9) Proof of Equations of motion by graphical methods
(10) Elementary idea of uniform circular motion
At the end of the video you will be able to answer the following:
1) Define motion in one dimension.
2) Describe Distance, Displacement, velocity, and speed.
3) Differentiate between Distance and displacement & Speed and Velocity
4) Solve problems based on the above
5) Draw Distance-time graph and velocity-time graph to define the relation between velocity, time and distance.
