Physical Science Momentum

Momentum is a _________ quantity.

• science
• scalar
• vector
• tensor

The momentum of an object depends on the object's __________ and  ____________.

• size and shape
• mass and energy
• mass and speed
• mass and velocity

A(n) __________ causes a change in momentum.

• impulse
• warp
• joule
• watt

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=1/2mv^2
• p=mgh
• p=mg

In any collision, the ____________ is always conserved.

• total momentum

• total speed

• total velocity

• energy

• more information is needed

A 50 kg ball rolls down the street at 5 m/s. Calculate the momentum of the ball. 

• 55 kg*m/s
• 100 kg*m/s
• 250 kg*m/s
• 500 kg*m/s

Two skaters begin at rest. Skater 1 has a smaller mass than Skater 2. After they push off each other,...

• Skater 1 experiences a greater change in momentum

• Skater 2 experiences a greater change in momentum

• Skater 1 has a greater speed than Skater 2

• Skater 1 experiences a greater force

Definition of impulse:

• The time integral of net force that causes Change in momentum

• The product of mass and velocity

• The ability to do work

• the rate of increase of speed or the rate of change of velocity
