Momentum

Momentum is a ____________________ quantity

• science
• scalar
• vector
• energy

The momentum of an object depends upon the object's ___________&_____________.

• size and shape

• mass and speed

• mass and veloctiy

• mass and energy

Determine the momentum of 1000-kg car moving northward at 20 m/s......... 

• 20000 N
• 20000 Joules
• 20000 Kg * m/s
• 20000 kg * m/s north

The definition of momentum is

• Mass in Motion
• The size of an object
• The velocity of an object
• A comparison between two objects

The equation to calculate momentum is

• p=mv
• p=1/2mv²
• p=mgh
• p=mg

What is the net force?

• 40 N left
• 0 N Balalnced
• 400 N right
• 40 N right

A 0.250 kg cart moving at 0.400 m/s has how much momentum?

• 0.1 kg-m/s
• 1 kg-m/s
• 10 kg-m/s
• 100 kg-m/s

When the speed of an object is doubled, its momentum

• remains unchanged in accord with the conservation of momentum.
• doubles
• quadruples
• decreases

A runner has a momentum of 670 kg m/s and is traveling at a velocity of 9 m/s. What is his mass?

• 74.4 kg
• 6030 kg
• 0.0134 kg
• 80 kg

A 2 kg cart has a momentum of 16 kg m/s. What is its velocity?

• 8 m/s
• 32 m/s
• 0.125 m/s
• 18 m/s
