The law of inertia, The law of acceleration, and the law of action-reaction.

Inertia is the property of matter that stays static unless something unbalanced disturbs it. Mass is related since the unbalanced force needs to force enough energy to disturb the object.

An example of the 3 Laws would be driving a car, Inertia plays a role whenever you accelerate or decelerate so does the law of acceleration, and the law of action reaction is applied when you sit on the car seat, exerting force onto the seat and the seat exerts force onto the car.

Newton's second law is the equation F=ma (force = mass times acceleration).

If you push an object it will accelerate, if the mass increases but he force stays the same it will accelerate less.
