1 AccelerationPage 11 of Scientific NotebookSection 2.2
2 Objectives: Describe Motion In Terms Of Changing Velocity. Compare Graphical Representations Of Acceleration.Apply Kinematic Equations To Calculate Distance And Velocity.
3 Spi’s and CLE’s:CLE.3231.Math.2 Solve for variables in an algebraic formula.CLE Investigate kinematics and dynamics.SPI Solve motion and conceptual problems regarding velocity, acceleration, and displacement
4 Velocity & Displacement Bellwork A doctor travels to the east from city A to city B (75 Km) in 1.0 h. What is the doctor’s average velocity?Show ALL WORK using the GUESS METHOD
5 What is Acceleration?The rate of change of velocity with respect to time.aavg = Change in velocitytime required for change
6 Read Page 50(3 minutes) Look at Figure 10 What is the Velocity at Point A?What is the Velocity at Point B?What is the Velocity at Point C?
7 What are the different types of acceleration? Velocity with Constant AccelerationDisplacement with Constant AccelerationVelocity & Displacement w/Constant AccelerationFinal Velocity After Any Displacement
8 Formulas for Constantly Accelerated Straight Line Motion See Page 58 of Physics Text BookCopy In Your Scientific Notebook
9 Guided PracticePage 12 of Scientific NotebookA car accelerates uniformly from rest to a speed of 6.6 m/s in 6.5 s. Find the distance the car travels during this time.21m
10 Guided PracticePage 12 of Scientific NotebookA driver in a car traveling at a speed of 21.8 m/s sees a cat 101 m away on the road. How long will it take for the car to accelerate uniformly to a stop in exactly 99m?9.1 s
11 Independent PracticeTurn in to TeacherA car enters the freeway with a speed of 6.4m/s and accelerates uniformly for 3.2 km in 3.5 minutes. How fast (in m/s) is the car moving after this time?24m/s
12 Independent Practice These will be taken up for a grade today. Turn in to TeacherThese will be taken up for a grade today.Please do your own work.Read Page 54; Then Look at Sample Problem D on page 55.Complete: Problems 1-4 Page 55
13 Closure: Did you Know?Decreases in speed are sometimes called decelerations. Despite the sound of the name, decelerations are really a special case of acceleration in which the magnitude of the velocity – and thus the speed - decreases with time.
