1. What is Motion?

2. Motion is an event that involves a change in the position or location of something.

3. How is motion described?
Motion is described in terms of speed, velocity, and acceleration.

4. Speed Speed is a comparison of time and distance.
Speed is expressed as distance traveled per unit time, for example miles per hour.

5. How do I find speed?
Speed is calculated using the following formula:
Speed is equal to Distance divided by Time.
The formula can be rearranged to solve for different variables.
S = d / t
T = d / s
D = s x t D S T

6. Constant Speed
Speed that does not change

7. So, exactly what is Velocity?

8. Velocity Speed AND direction
If my SPEED is 25 m/sec and I am traveling south, my VELOCITY is 25 m/sec south

9. What is Acceleration?

10. You may think that Acceleration means speeding up, but…

11. Acceleration is a change in velocity (speed or direction)
Acceleration is caused by unbalanced forces
There are many ways to accelerate…

12. Positive acceleration
Types of Acceleration
Speeding up
Positive acceleration

13. Negative acceleration
Types of Acceleration
Slowing down
Negative acceleration
Slowing down
Negative acceleration

14. Types of Acceleration
Stopping

15. Changing direction (turning)
Types of Acceleration
Changing direction (turning)

16. How do you calculate Acceleration?
(Final Speed – Initial Speed)
Time
Unit of measurement = m/s2
