1. the faster you go the more you have.
2. when moving things run into each other, is transferred.
3. all momentum added together after a crash should be to the momentum before the accident.
4. what two forces are acting on a rocket when it takes off?

a.
b.

1. what substance causes the ball to break?
2. conservation of says that whatever you put into a movement should be equal to the resulting movement.
3. rockets move because of the momentum of their
4. momentum depends on :

a.
b.

1. you and the car you are riding in both have.
2. why did bill put his foot on his croquet ball?
3. music quote: the faster you push me, the i get. your adding.

Explanation:

1. Momentum formula \( p = mv \) (mass \( m \), velocity \( v \)), so faster (higher \( v \)) means more momentum.
2. Law of conservation of momentum: when objects collide, momentum is transferred.
3. Law of conservation of momentum: total momentum before and after a crash is equal.
4. Rocket at take - off: thrust (from engines) and gravity (pulling down).
5. Assuming from context (common in such videos), carbon dioxide (e.g., in a pressure - related ball - breaking scenario).
6. Conservation of momentum principle.
7. Rockets move due to momentum of expelled gases (from engines).
8. Momentum \( p = mv \), so depends on mass (\( m \)) and velocity (\( v \)).
9. Both have momentum (as they are moving).
10. To stop its motion (change its momentum to zero).
11. Using momentum - related idea: faster push (more force, change in momentum), so “faster” (velocity) and “momentum”.

Answer:

1. momentum
2. momentum
3. equal
4. a. thrust; b. gravity
5. carbon dioxide
6. momentum
7. expelled gases
8. a. mass; b. velocity
9. momentum
10. To stop its motion.
11. faster; momentum
