H.W. Acceleration

Show your work

  1. What is the acceleration of a car that travels south and speeds up from 20m/s to 65 m/s in 30s?

2. If car A goes from 10 to 85 meters in an hour and car B goes from 5 to 25 meters in 20 mins. Who has the greatest acceleration?

3. Emely ran half of 3 meters in 10s , then twice that distance in 8 seconds. At the end of her race, she ran the last 15 meters in 15 seconds.

  • What was Emely’s  velocity during the first , second and last intervals, average velocity,  and acceleration?
  • Draw a graph for Emely’s race.

4. What is the difference between constant acceleration and constant velocity.

 

 

October Project

Using the following concepts each group will create an images only presentation. Each image will be utilized to explain each concept and answer questions in class. Keep in mind that for several concepts you can use only one image.

  • Frame of reference
  • Displacement
  • Positive displacement
  • Negative displacement
  • Velocity
  • Speed
  • Average velocity
  • Instantaneous velocity
  • Slope
  • Rise
  • Run
  • Acceleration
