8. Motion Chapter 10

9. Objectives
Explain the relationship between motion and a frame of reference.
Relate speed to distance and time.
Distinguish between speed and velocity.
Solve problems related to time, distance, displacement, speed, and velocity.

10. Motion
Motion (Quick Time Movie) = Object’s change in position relative to a reference point
Displacement = Change in the position of an object
Distance measures the path taken.
Displacement is the change of an object’s position. Displacement must always indicate direction.
Quick Time Movie Relative Motion

11. Distance Vs. Displacement

12. Velocity Objectives
Describe the concept of acceleration as a change in velocity.
Explain why circular motion is continuous acceleration even when the speed does not change.
Calculate acceleration as the rate at which velocity changes.
Graph acceleration on a velocity-time graph.

13. Speed and Velocity What’s the difference between speed and velocity?
Speed = How fast an object moves
Velocity = Speed in a given direction
Speed = Distance Traveled
