How forces affects motion
class 9 Chapter-6 (physics) In Chapter 4, you learnt to describe the motion of an object in termsof its position, velocity and acceleration. But you did not considerwhat causes motion. Is there an underlying cause for a change inposition and velocity of an object? What is the nature of this cause?Do all motions require a […]
