The equation to calculate momentum is

• p=mv
• p=1/2mv²
• p=mgh
• p=mg

Which has more momentum: a car stopped at a red light or a bike moving at 15 mph?

• car
• bike
• they are equal
• cannot determine using the info provided

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

• 20000 N
• 20000 Joules
• 20000 Kg * m/s south
• 10000 kg * m/s south

Momentum is a ____________________ quantity

• science
• scalar
• vector
• energy

In any collision (crash) the ______ is ALWAYS constant

• Total Momentum
• total speed
• total Velocity
• Energy

When two objects collide, the P_before is ____________ the P_after.

• more than 
• less than 
• equal to
• unrelated to

When the speed of an object is doubled, its momentum

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

Momentum is given by the formula p = mv. Choose the correct answer below :

• p = power , m = mass , v = velocity

• p = momentum , m = motion , v = volume

• p = power , m = mass , v = volume

• p = momentum , m = mass , v = velocity

The SI unit for linear momentum is :

• kg m s^-2

• kg m s^-1

• kg m s

• kg m^-1 s
