During an elastic collision, both energy and this are conserved.
What is momentum?
100
Impulse is change in this.
What is momentum?
100
This is the momentum of a 50-kg cart with a velocity of 2 m/s.
What is 100 kg m/s ?
200
This letter represents momentum.
What is 'p' ?
200
The unit for velocity.
What is 'm/s' ?
200
The total momentum before a collision equals this.
What is total momentum after a collision?
200
Impulse is force times change in this.
What is time?
200
This is the velocity of a 10-kg dog with a momentum of 5 kg m/s.
What is 0.5 m/s ?
300
The formula for momentum is this.
What is 'p = mv' ?
300
The unit for Force.
What is Newton?
300
If two cars with the same mass are heading at 60 mph into each other, what is their total momentum?
What is zero?
300
This is the impulse required for a 10-kg child that goes from rest to 4 m/s.
What is 40 kg m/s ?
300
This is the mass of a mystery object with momentum of 12 kg m/s and velocity of 2 m/s.
What is 6 kg ?
400
If you solve the momentum formula for velocity, you get this.
What is 'v = p/m' ?
400
The unit for momentum.
What is 'kg m/s' ?
400
A car going 30 m/s hits a stationary car of the same mass and they buckle together. This is their final speed as they slide together.
What is 15 m/s ?
400
An air bag protects you in a car by increasing the time it takes you to stop, which makes this smaller.
What is force?
400
This is the momentum required to take a 10-kg object from 2 m/s to 4 m/s.
What is 20 kg m/s ?
500
Force times change in time equals this.
What is impulse?
500
The unit for impulse.
What is 'kg m/s' ?
500
A car going 10 m/s hits another car of the same mass going the opposite way at 5 m/s. They bounce apart and the first car is going 4 m/s forward. This is the final velocity of the second car.
What is 1 m/s forward?
500
Between a car going from rest to 10 m/s and a cat going from rest to 15 m/s, this has the bigger impulse.
What is a car?
500
This is the force required to accelerate a 2-kg box from rest to 6 m/s in 3 seconds.
