5. Do Now  A bus travels between the 275 m marker and the 400 m marker on a highway in 20 s. The average speed of the bus during this interval is….  A soccer player kicks a ball at 32 m/s. If the goal is 10 m from the player approximately how much time does it take for the ball to reach the goal?

6. Physics Talk (Notes)  What is acceleration?  What is velocity?  Change in velocity with respect to time  Speed in a direction

7. Physics Talk (notes)  How can velocity change?  Increase or decrease in speed  Change in direction (turn)  So if velocity is changing…so is acceleration!

8. Physics Talk (notes)  What is positive acceleration?  What is negative acceleration?  Final velocity is more than initial velocity  Final velocity is LESS than initial velocity

9. Physics Talk (notes)  Describing acceleration using strobe photos  What is happening to the velocity and acceleration in this strobe photo?

10. Physics Talk (notes)  What is the equation for acceleration?  Acceleration = Δvelocity Δtime  a=Δv Δt ΔtΔt ΔvΔv a

11. Physics Talk (notes)  Practice Problem  At the start of a race, a toy car increases speed from 0m/s to 5.0m/s as the clock runs from 0s to 2.0s. What is the acceleration?
