1. Acceleration

2. Acceleration-the rate of change of velocity (remember: velocity=speed
Acceleration-the rate of change of velocity (remember: velocity=speed w/direction)
When the velocity of an object changes, the object is accelerating

3. Acceleration occurs when an object changes its speed, its direction, or both
If the speed is increasing—positive acceleration
If the speed is decreasing—negative acceleration (deceleration)

4. Ex. Of acceleration:
Horse on a carousel-IS ACCELERATING due to the constant changing direction of the horse’s circular motion

5. How to find Acceleration:
Equation:
Acceleration = change in velocity / time OR
Acceleration = final velocity – initial velocity / time
*Reported in m/s/s or m/s^2
If motion is in a straight line (no direction change), change in speed can be used to calculate velocity

6. Visualizing Acceleration-pg. 49
Amusement Park Acceleration
Wooden and Steel roller coaster provide different thrills due to different materials
Wooden—swaying effect
Steel-more loops, steep inclines, drops, etc.
