Newton’s First Law
An object will remain in its current state of motion, either constant speed or at rest, until it enters the presence of an unbalanced force to change its motion.

The soccer ball, acted upon by the normal force of a foot
kicking it, will go on forever with a velocity of 2 m/s
because Newton’s first law states that an object in
motion will stay in motion...
The soccer ball is at rest because the foot
serves as an unbalanced force, N,
on the ball.

Newton’s Second Law
The net force acting on an object is a result of the object’s mass multiplied by its acceleration.

The force of friction is acting on the bike, which allows it to move.
The imperfections in the tires’ surfaces and the road enable the friction force to affect the
motion of the bike.

Newton’s Third LawEvery action or force has an equal and opposite reaction and force. The forces are equal and opposite of each other at the point of contact.

The force of the volleyball on our arms is equal and opposite to the force of our arms on the volleyball.
The result of this action-reaction force pair can be seen from the red marks on a player’s forearms from
the volleyball.
