momentum and inertia

Momentum refers to the quantity of motion possessed by an object, taking into account both its velocity and mass. It is the tendency of an object to keep moving in the same direction unless acted upon by an external force. Inertia, on the other hand, is the resistance of an object to change its state of motion. It is a property of matter that allows objects to remain at rest or in uniform motion unless acted upon by an external force.
