What is the other name of Newton's first law of motion?
The first law of motion is also known as the law of inertia.
It is stated as:
An object remains in a state of rest or of
uniform motion in a straight line unless
compelled to change that state by an applied
force.The tendency of undisturbed objects to stay
at rest or to keep moving with the same
velocity is called inertia. This is why, it's called the law of inertia as well.
