Momentum and Impulse

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

• size and shape

• mass and size

• mass and veloctiy

• mass and energy

The equation to calculate momentum is

• p = m*v

• p = 1/2 m*v²

• p = m - v

• p = m + v

Which of the following has the MOST momentum? (they are all rolling at the same velocity)

• rolling ping-pong ball

• rolling bowling ball

• rolling soccer ball

• rolling basketball
