Compare speed and velocity.

• Velocity indicates only the direction of travel, but not the distance and time.

• Speed includes the direction of travel whereas velocity does not.

• Both velocity and speed indicate time and distance, but speed includes the direction as well.

• Both velocity and speed indicate time and distance, but velocity includes direction of travel as well.

How do you find the speed of an object?

• distance divided by time

• time divided by distance

• distance times time

• time times distance

Describe the motion at each point.
