What is Newton's third law?

• Every action has an equal and opposite reaction

• The net force on an object is equal to its mass times acceleration

• An object's quantity of motion is equal to its mass times velocity

• The net force is equal to the change in mass-times-velocity over time

What is the integral of the net force on an object over time? (i.e., what is the product of force and time?)

• Impulse

• Momentum

• Velocity

• Acceleration
