Question

Define force.Why is newton's first law of motion called law of inertia..??

Answer 1

Answer:

A Force is that physical cause which changes or tends to change either the size or the shape or the state of rest or of motion of the body.

Explanation:

Newton's first law of motion is also called law of inertia because Force is qualitatively defined as Force is that external cause which tends to change the state of rest or the state of motion of an object.

Answer 2

Newton's first law, also called the "law of inertia", states that an object at rest remains at rest, and an object that is moving will continue to move straight and with constant velocity, if and only if there is no net force acting on that object.
