Momentum Basics
Aside from mass, this is also going to contribute to an object's momenum.
What is velocity?
This is the formula for Impulse.
What is J = Ft?
This is the momentum of a 12kg cart moving 10m/s.
What is 120kgm/s?
This is what we call a collision where two separate objects collide and travel together as one.
What is inelastic?
This is what the "P" originally meant for P=mv.
What is "to Progress"?
This is the amount of momentum a stationary kangaroo has.
What is zero?
This is another way to describe Impulse.
What is "change in momentum"?
This is how fast a 200kg scooter needs to be moving in order to have the same momentum as a 400kg horse trotting at 3m/s.
What is 6m/s?
Two equal mass objects collide and bounce off of one another.
This is what happens to object B if object A is moving, hits stationary object B and then object A is stationary.
What is transfer the momentum to object B causing it to move?
This is the reason (physics concept) that pole vaulters land on big mats.
What is to increase the stopping time and reduce the force, similar to a crumple zone?
This is the formula for momentum.
What is P = mv?
If the time that an impulse is experienced gets shorter, this is what happens to the force.
What is increase or gets larger?
This is the mass of a cart that is rolling at 4m/s is if it has a momentum of 620kgm/s.
What is 155kg?
This is why cannons weigh so much more than the cannonball they launch.
What is it prevents the cannon from getting shot backwards....this is recoil, by the way.
This is why bouncing applies more force.
What is Final - Initial velocities add up to increase the change in momentum? (or something that means this)
If the velocity increases while mass says the same, this is what happens to momentum.
What is increases?
In order for the force experienced during an impulse to be reduced, this is what must happen to the time it is experienced.
What is increase or get longer?
This is the force required to stop a 1200kg cart that is traveling at 6m/s if the stop only takes 3 seconds.
What is -2400N?
This is the relationship between the left and right side of the equations (before and after the collision) because of the Law of Conservation of Momentum.
What is "they are equal"?
This is the other law of conservation that relates to the law of conservation of momentum.
What is the Law of conservation of ENERGY?
If the velocity increases while mass decreases, this is what happens to momentum.
What is stays constant?
In the car crash video, this is the example that is used to explain how the force on an occupant is reduced during a collision.
What is airbags, seatbelts or crumple zones?
This is how long it takes you to stop a 600kg baby elephant running at 3m/s if you apply -100N of force.
What is 18 seconds?
What is inelastic?
This is how much force will be applied to the brakes to bring a 3000kg vehicle from 10m/s to 8m/s in 3 seconds.
What is -2000N?
