Q. Define the term kinematics? and Distinguish between rest and motion?
Kinematics
The branch of physics that deals with the description of motion of objects without reference to the force or agents causing motion is called kinematics.
Rest and Motion
If a body does not change its position with respect to its surroundings it is said to be at rest and if a body keeps on changing its position in relation to its surroundings, it is said to be in motion. Rest and motion are relative states of a body.
