Describe what acceleration means in terms of motion.

• The speed at which an object moves

• The change in speed or direction over time

• The distance an object travels

How can you tell if an object is accelerating?

• If it is moving at a constant speed

• If its speed or direction is changing

• If it is at rest

What does it mean if an object has a constant velocity?

• The object is not moving

• The object's speed and direction are not changing

• The object's speed is changing but its direction is not
