1. Motion
Motion - the displacement of an object in relation to objects that are considered to be stationary.

2. Motion
Motion - the displacement of an object in relation to objects that are considered to be stationary.
Displacement - a change of position in a particular direction (a vector quantity).

3. Motion
Speed - the time rate of motion.

4. Motion Speed - the time rate of motion.
Average Speed - dividing the total distance by the elapsed time.

5. Motion Speed - the time rate of motion.
Average Speed - dividing the total distance by the elapsed time.
Instantaneous Velocity – the velocity measure at this time.

6. Motion
Velocity - speed in a particular direction (a vector quantity).

7. Motion Velocity - speed in a particular direction (a vector quantity).
Average Velocity - the total velocity divided by the total elapsed time.

8. Motion Velocity - speed in a particular direction (a vector quantity).
Average Velocity - the total velocity divided by the total elapsed time.

9. Motion
Instantaneous Velocity - the speed and direction of a moving body.

10. Motion Example - DISPLACEMENT
When you leave for school in the morning you notice a car across the street from your house. When you return in the evening, the car is in front of the next house, about 50 feet to the East. Describe the displacement that this car has experienced.

11. Motion
Example - Speed
One weekend, you make a trip to see friends. Your trip of 142 miles takes 2 hours and 15 minutes. What is your average speed on this trip?

12. Motion Example - Velocity
A small plane is traveling toward the East at 155 km/h. It encounters a wind blowing toward the East (a tail wind) at 35 km/h. What is the velocity relative to an observer on the ground?
