Question

P1: Explain in detail - How can the motion of an object that is already moving change? (What are the different ways a moving object can change its movement?)​

Answer 1

Inertia: tendency of an object to resist changes in its velocity. An object at rest has zero velocity - and (in the absence of an unbalanced force) will remain with a zero velocity. Such an object will not change its state of motion (i.e., velocity) unless acted upon by an unbalanced force.
