Compare the "total momentum before" of both carts or balls and "total momentum after" for the ELASTIC collisions #1, 2 and 3. What happened to the total momentum of both objects after the collisions?
Compare the total kinetic energy of both carts/balls before and after the ELASTIC collisions. What happened to the total energy after the elastic collisions?
Compare the "total momentum before" of both carts/balls and "total momentum after" for the PERFECTLY INELASTIC collisions. What happened to the total after those collisions?
Compare the total kinetic energy of both carts before and after the PERFECTLY INELASTIC collisions. What happened to the total ENERGY after those collisions?
What do you notice about the change in momentum of each individual object in ALL collisions? Compare the red cart to the blue cart or the blue ball to the pink ball.
What is another difference between elastic and perfectly inelastic collisions?
Elastic collisions always have less total momentum after, inelastic always have the same total momentum
Elastic collisions always have the same total energy before and after, inelastic collisions have less energy after
Elastic collisions always have less total energy after, inelastic collisions always have the same total energy before and after
In Perfectly Inelastic collision #1, how does the final velocity of the blue ball compare to the initial velocity of the blue ball?

If the total final momentum of both objects after an explosion is 0, how can both objects be moving?
In both of the explosions, what happens to the total energy of both objects after the explosion compared to before?
increased
decreased
is 0
remains constant
Which of these are true about inelastic collisions and perfectly inelastic collisions? Select all that apply.
Perfectly inelastic stick, inelastic do not stick
Perfectly inelastic do not stick, inelastic do stick
In both types, the total energy decreases after the collision.
In perfectly inelastic, the total momentum before and after remains constant. In inelastic, the total decreases.
In both types, total momentum before and after are the same.
Look at perfectly inelastic collision #1, how do the velocity of the blue ball and pink ball compare after they collide?
They are the same because they are stuck together
The more massive ball has a higher velocity
The less massive ball has a higher velocity
The final momentum of each pink ball is always equal to the initial momentum of each pink ball in all collisions.
True
False
Conserved means the total amount remains constant. Momentum is conserved in (a) collisions without outside forces like friction.
Conserved means the total amount remains constant. Kinetic energy is conserved in (a) collisions without outside forces like friction.
Review: Follow through is when you (a) time by bringing your arm back in order to increase impulse which increases change in (b) . Higher momentum means more velocity.
When you catch during egg toss, you want to increase the (a) of your catch so that the force (b)
When you are stopping an egg, you can make the change in momentum smaller by exerting less force.
True
False
