Q

Newton’s second law of motion

A

States that the acceleration of an object is in the same direction as the net force on the object and that the acceleration equals the net force divided by its mass

Q

Newton’s third law of motion

A

States that when one object exerts a force on a second object the second object exerts a force on the first object that is equal in strength and in the opposite direction
