If an object travels 80 meters in 20 seconds, what is its speed?

• 4 m/s

• 2 m/s

• 0.25 m/s

• 100 m/s

What does displacement measure?

• Total time

• Total path traveled

• Straight-line change in position

• Average force

What does acceleration describe?

• A change in color

• A change in velocity

• Distance moved

• Object’s mass

What is the formula for acceleration?

• a = v × t

• a = d ÷ t

• a = (v_f - v_i) ÷ t

• a = m × a

The unit for acceleration is:

• m/s

• m²

• m/s²

• km/h
