Hallo dear!!!

Gd morning

Have a nice day ahead!!!

Motion is a change in position of an object over time.

An object's motion cannot change unless it is acted upon by a force

There are total three laws of motion:

First law: In an inertial reference frame, an object either remains at rest or continues to move at a constant velocity, unless acted upon by a net force.

Second law: In an inertial reference frame, the vector sum of the forces F on an object is equal to the mass m of that object multiplied by the acceleration a of the object: F = ma.

Third law: When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body.
