What do the arrows or vectors represent?

• Forces acting on the object

• All the acceleration acting on the object

• All the ways an object can move

• Down

• Left

• Right

What is the changing of position over time?

• motion

• reference point

• acceleration

• speed

A place or object used for comparison to determine if another object is in motion is called a

• comparison point

• reference point

• point of view

• motion detector

Choose the answer that best fits: Acceleration is the...

• change of speed and/or direction over time

• change of speed over time

• change of direction over time

• increase of speed

What do motion diagrams typically represent in physics?

• The path of an object over time

• The forces acting on an object

• The energy changes in a system

• The temperature variations in a system

In a motion diagram, what does a longer arrow typically indicate?

• Greater speed

• Greater mass

• Greater force

• Greater time interval
