What law states that if you push on a wall with 100N, the wall will push 100N back on you?
Newton's Third Law of Motion
What does Newton's First Law of Motion state?

2x
Identify the reaction in the example.
Student punches another student in the face
The "another" student's face pushes back on the student's fist
Force acting on per unit area is known as
pressure
Which law states if requires more force to accelerate something if it has more mass?
Newton's Second Law of Motion
What does Newton's Third Law of Motion state?
Every action has a equal and opposite reaction

390N
Which law applies to a pencil resting on a desk?
All laws of motion apply
What does Newton's Second Law of Motion state in words?
The time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it.
