What governs the motion of bodies?
Uniform motion needs the concept of velocity alone whereas non-uniform motion requires the concept of acceleration in addition.
In this course we explore the basic question: what governs the motion of bodies?
How are things set in motion? What are the forces that can influence their motion?
A force is required to put a stationary body in motion or stop a moving body, and some external agency is
needed to provide this force. Some external forces such as gravitational force or magnetic force have the ability to exert force on a body even without being in contact with it.
