Motion Test

Marissa and her family travel from Madison, Wisconsin to Minneapolis, Minnesota. When Marissa divides the total distance they traveled by the total time they were traveling, she is calculating their:

• instantaneous speed

• constant speed

• average speed

• variable speed

What is the difference between speed and velocity?

• speed has both a size and a direction

• velocity has both a size and a direction

• velocity and speed are the same thing

• velocity has a distance while speed has a position

Speed is:

• calculated by dividing the distance traveled by the time taken

• zero for all objects at rest

• a measure of how quickly an object gets from one place to another

• all answers are correct
