Calculate the momentum of an object that weighs 5 kg that is moving at a rate of 3 m/s
15 kg*m/s
This is inertia in motion.
What is momentum?
This quantity is conserved before and after a collision occurs
What is the Law of Conservation of Momentum?
Calculate the mass of an object with a momentum of 15 kg*m/s that was moving at a rate of 5 m/s
3 kg
This is the act of momentum being changed over time
What is impulse?
If momentum changes, but the mass stays the same, what can be said about the velocity?
About 12.8 m/s
This is the act of force being applied at an instant
What is impact
A truck at rest with a mass of 20,000 kg is compared to a mouse with a mass of 0.3 kg moving at a rate of 2 m/s. Which one has a larger momentum?
Mouse
4 m/s
This collision is exhibited in a game of billiards when two balls collide
What is an elastic collision?
A spit wad is shot from a long straw. Another spit ball is shot from a shorter straw. Which spit wad will travel further and why?
Long straw; it experiences more impulse
A ball is rolled down a hill. It has a mass of 3 kg and a velocity of 14 m/s. A spring causes the bowling ball to be launched back at a velocity of 6 m/s.
What is the change in momentum, and if the force of impact lasted for 4 seconds, how much force was applied to the bowling ball?
-36 kg*m/s, 1/9 N
This type of collision occurs when a train cart connects itself to another train cart.
What is an inelastic collision?
This type of collision causes the most damage.
What is a bounce/ what is elastic collisions
