• speed
• acceleration
• favorite food

The graph shows Ashley riding her bike to Maria's house.

What is occurring from point A to point B?

• they are traveling at a constant speed

• they are decreasing in speed

• they stopped to take a break

The graph shows Ashley riding her bike to Maria's house.

What was occurring from point B to point C?

• She was increasing her speed.

• She stopped for 4 minutes

• She was decreasing in speed

What is velocity?

• Time + Distance

• Speed in a given direction

• A fast dinosaur

• The direction a storm is moving

The rate at which velocity CHANGES is:

• acceleration

• speed

• direction

• physics
