Velocity is another name for speed. 2 Speed and Velocity Disagree. Velocity includes both speed and direction.
What is speed? 2 Speed and Velocity Speed is the distance an object moves in a unit of time.
How can you use a distance-time graph to calculate average speed? 2 Speed and Velocity You can calculate an object’s average speed from a distance-time graph by dividing the distance the object travels by the total time it takes to travel that distance.
What are ways velocity can change? 2 Speed and Velocity Velocity changes when speed, direction, or both speed and direction change.
