Graphing Motion: Distance, Velocity, and Acceleration

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

3
August 27, 2012 HW: 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 ABCD

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?

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
