Newton's First Law:This law states that an object at rest will stay at rest, and an object in motion will stay in motion with constant velocity, unless acted upon by an external force.
Momentum:Momentum is the product of an object's mass and velocity. It describes how difficult it is to stop or change the motion of an object.
Friction:Friction is a force that opposes the relative motion between two surfaces in contact. It can affect an object's inertia by slowing it down or stopping it completely.
