Momentum practice

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

• size and shape
• mass and speed
• mass and veloctiy
• mass and energy

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
