When an object changes its position with respect to time, then the body is said ti be in 'motion'. When the body is at rest, it is state of 'no motion'.
the motion in any specific direction following any path in the action of force is called balanced motion . Where as the motion in an y direction due to the force is called unbalance motion motion.
All motion is relative. The question "is this object moving?" is in fact meaningless unless we specify "moving relative to what other object". Similarly, there is no such thing as "absolute rest":...
"Acceleration" means a change in velocity. And "velocity" is a vector - meaning that not only the magnitude, but also the direction is relevant. So, if the direction of the movement changes, the...
