Activity E.1 Review

All graphs should include...

• X-axis

• Y-axis

• Title

• Labels

What does speed tell you?

• how fast an object is moving

• the direction an object is moving

• both

What does velocity tell you?

• how fast an object is moving

• the direction an object is moving

• both

Which is a vector?

• speed

• velocity

How is direction change indicated on a velocity time graph?

• by the graph crossing the X-axis

• by the graph crossing the Y-axis

• there is no way to indicate change in direction

• positive velocity

• negative velocity
