Newton’s Laws of Motion — Chapter Summary

Inertia is the property of

Inertia is the property of an object to resist any change in its state of rest or uniform motion. It depends only on the mass of the object — the grea

An object remains at rest

An object remains at rest or in uniform motion in a straight line unless acted upon by a net external force. This law introduces the concept of inerti

The rate of change of momentum

The rate of change of momentum of a body is directly proportional to the net external force acting on it and occurs in the direction of the force. Mat

For every action

For every action, there is an equal and opposite reaction. When one object exerts a force on another, the second object exerts an equal and opposite f

In an isolated system where no

In an isolated system where no external forces act, the total momentum before and after an interaction remains constant. This principle applies to col
