  1. Graphing Motion: Distance, Velocity, and Acceleration Physics Chapter 1, Section 4

  2. Do Now • With a partner grab 1 Speed Machines worksheet from the front table. Work the problems together

  3. August 27, 2012HW: PTG #1-11, pg 68/69 skip 10 Due Friday • Do Now (NB pg 15 ): • 1.3 Quiz • WDYS • WDYT • TB Pg 52 • Success Criteria • Define acceleration using words and equation • Calculate speed, distance, and time, using the equation for acceleration • Interpret distance-time and velocity-time graphs for different types of motion • Agenda: • Do Now • Physics Talk Notes • Practice Problems • Acceleration Relay • Quiz 1.4

  4. Of the 4 different distance vs time graphs, indicate which fit the below descriptions 1____ No motion 2____ constant speed 3____ faster motion at the beginning 4____ faster motion at the end A B C D

  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 Δv a Δt

  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?

  12. Physics Talk (notes) • Describing acceleration using Graphs

  13. Physics Talk (notes) • Comparing motion Graphs

  14. Physics Talk (notes) • Practice Problems

  15. HW:PTG #1-11, skip 10 • Do Now (NB pg 15 ): • Get out signed grade report • Finish Formula Challenge (10 min) • Success Criteria • Define acceleration using words and equation • Calculate speed, distance, and time, using the equation for acceleration • Interpret distance-time and velocity-time graphs for different types of motion • Agenda: • Do Now • Physics Talk Notes • Practice Problems • Acceleration Relay • Quiz 1.4
