Momentum

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 equation to calculate momentum is

• p=mv
• p=1/2mv²
• p=mgh
• p=mg

A runner has a momentum of 720 kg m/s and is traveling at a velocity of 5 m/s. What is his mass?

• 14.4 kg
• 1400 kg
• 144 kg
• 360 kg

When the speed of an object is doubled, its momentum

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