MOMENTUM AND IMPULSE

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

• 
  size and shape

• mass and speed

• mass and velocity

• mass and energy

The equation to calculate momentum is

• 
  p=mv

• p=1/2mv²

• p=mgh

• p=mg

• car

• bike

• 
  they are equal

• cannot determine using the info provided
