2 balls collide and bounce off of each other. During the collision total momentum remained constant and total kinetic energy remained constant. What type of collision is this?
Inelastic Collision
Elastic Collision
Perfectly Inelastic Collision
No collision occurred
A BMW rear ends a car at the stop light. Neither car sticks together. The momentum was conserved in the collision but the kinetic energy was not conserved. What type of collision is this?
Elastic Collision
Inelastic Collision
Perfectly inelastic Collision
No Collision
If a collision is elastic which of the following must be true?
Momentum is not conserved
The objects are in an open system
The total momentum is equal to 0
Kinetic Energy is conserved
If there is a perfectly inelastic collision, which of the following must be true?
The total momentum of the system is 0
The total kinetic energy of the system is conserved
The objects stick together after colliding
The total momentum of the system is not conserved
Two carts collide. They stick together and continue moving. Is momentum conserved in this interaction?
Yes
No
Two metal balls collide in an elastic collision. Is momentum conserved in this collision?
Yes
No
What two variables effect momentum?
mass
weight
height
Velocity
What is the equation for momementum?
p=m×v
p=m×a
p=f÷a
m=p×v
A 2 250 kg Tesla going 15.0 m/s collides with a parked 3 190 kg Dodge Ram. During the collision they stick together as they deform. The two vehicles then travel at 6.20 m/s.
What is the momentum of the Tesla before the crash?
14,000 kg m/s
19,800 kg m/s
33,800 kg m/s
47,900 kg m/s
What word can best describe the total momentum in an isolated system?
constant
large
lost
low
The Law of Conservation of Momentum states:
The total momentum before a collision is equal to the total momentum after a collision.
The total momentum before a collision is greater than the total momentum after a collision.
The total momentum before a collision is less than the total momentum after a collision.
The total momentum before a collision is not related to the total momentum after a collision.
