Examples include the difference in impact between a table tennis ball hitting a player (little to no harm) compared to a fast-moving cricket ball hitting a spectator (potential harm). Similarly, a stationary truck poses no threat, but a moving truck, ...

The acceleration of an object is directly proportional to the force applied to it. This means that the greater the force applied, the greater the acceleration experienced by the object, according to Newton’s second law of motion.

The first law of motion states that when an unbalanced external force acts on an object, its velocity changes, resulting in acceleration.

No, all bodies do not have the same inertia. Inertia depends on the mass of the object; the greater the mass, the greater the inertia.

Inertia and mass are closely related, with mass serving as a measure of an object’s inertia. The greater the mass of an object, the greater its inertia, and therefore its resistance to changes in motion or rest.
