ACCELERATION

2
WHAT DO WE DO WHEN MOTION LOOKS LIKE THIS?

3
Velocity is NOT constant! What does this mean is happening?

4
ACCELERATION …a change in velocity

5
NEW VARIABLES avfvivavfviv

6
KINEMATIC EQUATIONS

7
PRACTICE #1 A car slows from 22m/s to 3.0 m/s at a constant rate of 2.1 m/s 2. How many seconds are required before the car is traveling at 3.0 m/s?

8
PRACTICE #2 A student is leaving the CHS parking lot after school. He starts his car and accelerates uniformly for 5.32 seconds over a distance of 195 m (it is Friday afternoon). What is the acceleration of the sports car?

14
GRAPHS FOR DROPPED OBJECT

15
FREE FALL Definition? Only force acting is gravity Up and down Forces cause acceleration

16
ACCELERATION DUE TO GRAVITY Same for all objects Does not depend on mass, height Ignore air resistance - 9.8 m/s 2 Why negative?

17
FREE FALL PROBLEMS Up is positive, so down is negative Same tools ( replace “a” with “g” in equations)
