3. SPEED AND VELOCITY NOTES

4. Distance is a measure of how far an object has moved and is independent of direction.
If a person travels 40m due east, turns and travels 30m due west, the distance traveled is 70m.

5. Speed is how fast something is going
Speed is how fast something is going. It is a measure of the distance covered per unit of time and is always measured in units of distance divided by units of time. (The term “per” means “divided by”) example m/s

6. Speed is a rate as it is a change (change in distance) over a certain period of time.
Speed is independent of direction.

7. The speed of an object can be described two ways:
Instantaneous speed is “the speed at a specific instant”.
Average Speed is an average of the speed of an object during a period of time.

9. Velocity has speed and direction!

10. In the equation, “v” can represent either velocity or speed and “d” can represent either displacement or distance, depending on the context of the problem.

11. The term “speed” or “velocity” refers to average speed or velocity.
You must determine the “given” information in a problem using the correct units.
Using the formula, v = d/t,
you must be able to calculate average speed.
