A vector is a quantity with... (choose all that apply)

• magnitude

• mass

• direction

• speed

Match the following quantities to their units.

• sec

• time

• m/s

• velocity

• meters

• displacement

Which of the following are two examples of vectors?

• force, distance

• speed, mass

• time, acceleration

• velocity, displacement

What is DISPLACEMENT?

• Where a moving object starts

• The time it takes to get from point A to point B.

• How far away a moving object is from where it started.

• The position at which a moving object is located.

What is the best description for the motion in this distance v. time graph?

• An object is not moving

• An object is moving backward at a constant speed

• An object is moving forward at a constant speed

• Object is speeding up in the forward direction
