Momentum is a ____________________ quantity

• science
• scalar
• vector
• energy

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

• size and shape

• mass and speed

• mass and veloctiy

• mass and energy

• 20000 N
• 20000 Joules
• 20000 Kg * m/s
• 20000 kg * m/s north
