Force is measured in:

• Einsteins

• Newtons

• Pounds

• Kilograms

Explain what a frame of reference is (think about the skateboarding video we watched in class).

Mass has no effect on air resistance, so two bottles of different mass can be dropped and hit the ground at the same time. What DOES have an effect on air resistance?

• weight

• attitude

• surface area

• color

Select everything that friction can do (multiple answers):

• slow motion

• stop motion

• increase speed

• create heat
