Conservation of Momentum

-The Law of Conservation of Momentum states tha the total momentum of any group of objects that interact do not change.

-When two objects collide in the absence of fricton, momentum is not lost.

Do Action-Reaction Forces Cancel?

*Newtons Law refers to individual forces and their opposites. That is why it is possible for two skaters to push off of each other and not end up the same distance from their starting point.*

.If one skater had more mass than the other, it would take more force to puch them and they wouldn't travel as far.

Newton's Third Law of Motion

-When one object exerts a force on a second object exerts an equal but opposte force on the force.

.forces are equal and oppposite but act on different objects.

.they are not "balenced forces"

ex).the movement of the horse depends on the forces acting on the force

ACTION-REACTION PAIRS

-The rocket exerts a downward force on the exhaust gases.

-The gases exert an equal but opposite upward force on the rocket.

-both objects accelerate

-The amount of acceleration depends on the mass of the object
