momentum
what is a quantity that describes the net force applied to an object for some amount of time?
What is Impulse.
Elastic collision is defined as one in which this quantity is conserved
What is kinetic energy?
The units for impulse and momentum. (these units mean the same thing since impulse = change in momentum)
what are kg*m/s and N*s?
What is the impulse formula?
What is impulse = Force*time
the classification of type of collision where there is a loss in kinetic energy.
What is inelastic collision?
a cat that has a momentum of 125 kg*m/s as it falls from a ladder with a velocity of 12.5m/s would have this much mass
What is m=10kg?
The change in momentum on a tennis ball that is hit with an impulse of 20N*s.
What is -20kg*m/s
caused by an impulse
What is the change of momentum?
The type of collision where two objects hit and stick together
What is a completely or perfectly inelastic collision?
The impulse on a golfball that has a change in momentum of 45 kg*m/s.
What is 45 N*s?
Which of the following is not the same magnitude on both objects in a collision? Force, time, ∆v, ∆P, impulse
What is change in velocity?
This quantity is conserved in all collisions
What is momentum?
A 12kg car has a change in momentum of 240kg*m/s. If its final velocity is 3m/s, this would be its initial velocity.
What is -17m/s?
the change in momentum of a baseball hit with an impulse of 60 N*s
What is 60 Kg*m/s?
This property of a force v. time graph represents the impulse.
What is the trapped area?
This quantity is conserved in elastic collisions
What is kinetic energy?
the units for momentum.
What are kg*m/s?
The impulse on a car that has a change in momentum of 12,000 Kg*m/s.
What is 12,000 N*s?
