How much force is needed to change motion is called...

• mass

• final velocity

• initial velocity

• time

• momentum

• mass

• final velocity

• initial velocity

• time

• momentum

Describe what each letter stands for in the momentum equation.

What is A, B, and C?

• A= 5 kg m/s

  B= 50 kg

  C= 40 m/s

• A= 50 kg m/s

  B= 5 kg

  C= 4 m/s

Which object from #4 has the least momentum?

• A

• B

• C

How does the momentum of object A compare to the momentum of object B?

• Object A has less momentum

• Object B has less momentum

Why is the momentum of object B greater than the momentum of object C?

• The "mass" is much greater

• The "velocity" is much greater

• The "momentum" is much greater

What is the momentum of a 50 kg shark swimming at a rate of 10 m/s?

• p = 50 kg x m/s

• p = 500 kg x m/s

• p = 5 kg x m/s
