Acceleration of an object occurs when the object...

• Slows down

• Speeds up

• Changes direction (turn)

• All of the above

What does a negative slope mean on a position vs time graph?

• The object is not moving at all.

• The object is slowing down.

• The object is moving at a constant speed back to where it started.

Which graph shows a car that has a negative acceleration?

• A

• B

• C

• none of them

The velocity-time graphs represent the motion of four different objects. Identify the object that is stationary or not moving.

One difference between speed and velocity is that velocity includes a(n) _____________________ (like N,S,E,W) and speed does not.
