Answer:
Inertia
Step-by-step explanation:
The tendency of an object to resist any change in its motion is known as its inertia. The first law of motion is also known as the law of inertia. The inertia of an object can change its speed and the direction of motion. It is related directly to the mass of an object.
A body having more mass will have more inertia while a body having less mas will have less inertia.
