• Acceleration due to gravity

How are speed and velocity alike?

• Speed and velocity both have direction.

• Speed and velocity both tell how fast something is traveling.

• Speed and velocity are both vectors.

• Speed and velocity are both measured in m/s.

True or False: Velocity is a vector and tells direction. Speed is scalar and only tells quantity.

• True

• False

What axis is time ALWAYS graphed on?

• X-axis

• Y-axis

• It depends on the graph
