The property of an object by virtue of which it cannot change its state of uniform motion along a straight line or rest on its own is called as inertia. It is the measure of the mass of a body.
There are 3 types of inertia:
- Inertia of rest
- Inertia of motion
- Inertia of direction
Force: A force is a push or pull upon an object resulting from the object's interaction with another object.
Newton's Laws of Motion
- First Law: A body continues in its state of rest or of uniform motion in a straight line unless it is compelled by some external force to change that state.
- Second Law: The net force produced by an object is directly proportional to the magnitude of the net force and takes place in the direction of the force.
- Third Law: To every action, there is an equal and opposite reaction.
