A newtons 1st law of motion can also called inertia and an newtons 1st law states that an object that is not moving or is at rest stays at rest and an object that is in motion stays in motion unless it is acted by an unbalanced force

Inertia is the resistance of any physical objectto any change in its state motion including change to its speed and direction.
interaction- an action that has an equal effect on two or more object (in every action there is an equal force of interaction)
acceleration- the rate which  the velocity of an object changes over time
