1. 2-2 Acceleration At the start of a race what happens?
As you go down the interstate and go on the exit what happens?

2. Acceleration is the rate of change of velocity.
change speed - accelerate
change direction - accelerate
acceleration has direction
speed up - positive
slow down - negative

3. Calculation of Acceleration
Divide the change in velocity by the change in time

4. D is the Greek symbol delta
means “change in”
units for acceleration
m/s2 (meters per second squared)

5. Distance Equation
How far did the object travel during the acceleration

6. Acceleration due to Gravity
The force of attraction between Earth and object causes an acceleration
This is a constant value for all objects
g = 9.8 m/s2
