NGSS.MS-PS2-2

A type of friction that occurs when air pushes against a moving object causing it to decelerate.

• surface area

• air resistance

• velocity

• gravity 

How do the magnitudes of static and kinetic friction compare?

• They are equal

• The magnitude of kinetic friction is greater

• The magnitude of static friction is greater

What is the equation that links extension, force applied to a spring and spring constant?

• force applied to a spring = spring constant x extension

• force applied to a spring = spring constant ÷ extension

• force applied to a spring = extension ÷ spring constant

What is the equation that links acceleration, mass, and resultant force?

• resultant force = mass x acceleration

• resultant force = mass ÷ acceleration

• resultant force = acceleration ÷ mass
