Question

What is motion? Differentiate between slow and fast objects.

Answer 1

An object that changes its position with respect to time and another object is said to be in motion. Motion can be quantified by a quantity known as speed which is defined as the distance covered by an object in a specific interval of time.
An object which takes longer time to cover a certain distance is called slow whereas another object which takes shorter time to cover the same distance is called fast.
