An object's kinetic energy is directly related to what 2 things?

• Speed

• Distance

• Motion

• Mass

What is the correct formula used to calculate kinetic energy (KE)?

• KE = mass x speed (KE = mv)

• KE = 2 x mass x velocity2 (KE = 2mv2)

• KE = 1/2 x mass x speed2 (KE = 1/2mv2)

• KE = time x mass (KE = tm)
