• force

• gravity

• acceleration

Acceleration is defined as the CHANGE in 

• time it takes for one place to move to another place. 
• velocity of an object.
• distance divided by the time interval 
• velocity divided by the time interval 

A negative acceleration means that your object is _____. 

• not accelerating
