Total questions: 10
Worksheet time: 50mins
Which of the following statements is true about momentum?
Momentum is a vector quantity.
The standard unit on momentum is the Joule.
An object with mass will have momentum.
An object can be traveling eastward and slowing down; its momentum is westward.
How to find momentum?
KE=p^2/2m
J=F(t)
P=mv
M1V1+M2V2=(M1+M2)Vf
Choose all the types of collisions.
Elastic collision
Completely Elastic
Totally inelastic
Inelastic collisions
What is the equation for completely inelastic?
M1V1+M2V2=M1V1+M2V2
M1V1+M2V2=(M1+M2)Vf
K1+K2=K1+K2
P=mv
What are the characteristics of Inelastic Collisions?
Total Kinetic energy is not conserved
Total kinetic energy is conserved
Total momentum is not conserved
Total momentum is conserved
What are the characteristics of Elastic collisions?
Total momentum is conserved
Total momentum is not conserved
Total Kinetic energy is conserved
Total Kinetic energy is not conserved
If the speed and mass of an object are doubled, which of the following is true?
The momentum of the object is doubled
The kinetic energy of the object is doubled
The momentum of the object is quadrupled
The kinetic energy of the object is multiplied by 8
An object of mass 4 Kg is moving towards the east at a velocity of 6 meters per second. It collides and sticks to a 6-Kg object moving with a velocity of 5 meters per second in the same direction. How much kinetic energy was lost in the collision?
1.2 J
4.25 J
0 J
2.4 J

30 m/s
15 m/s
0 m/s
12.5 m/s
A 10kg ball moving at 13 m/s strikes a 20kg ball at rest. After the collision the 10kg ball is moving with a velocity of 7 m/s. What is the velocity of the second ball?
3 m/s
12 m/s
6 m/s
4 m/s
