2-6+Acceleration

Print out a list of the instructions ([|Acceleration_Gravity.pdf]) and staple it to the work for this section. On the top, write your name and the due date: **May 15th.**

1. NOTES Section
//on separate papers (either printed or typed), please make notes, using the following questions as a guide. If you want to answer the questions instead, either a) write the questions out, then answer in short form, or b) answer in complete sentences//

LEARNING RESOURCES: [|Acceleration for beginners], [|Physics Classroom], **//Nelson//** textbook section 12.5 (p.462) and glossary. . a) What is __acceleration__? . b) Explain why you know there is acceleration for each of the following: ........ a truck rolling down a hill (if you don't step on the brakes) ........ stepping on the gas pedal of a car and the car passes another ........ a skier going __straight down__ a ski hill ........ a skateboarder going down a ramp (like the following): . c) Often, we say words like 'speeding up, or accelerating' (when we step on the gas) and 'slowing down, or decelerating' (when we step on the brake). Why do both these terms really mean "acceleration"? . d) Use the [|animations] to answer these questions: . e) We've seen that the units for distance is "m" (for metres), the units for time is "s" (for seconds), and the units for speed are "m/s" (or metres per second). What are the units for acceleration? . f) What is the formula for acceleration? ..
 * explain why the green and blue cars accelerate, but the red car doesn't. Which accelerates the most?
 * on a distance-time graph (referred to as a 'position-time' graph on this page), what does acceleration look like? (SKETCH a 'distance-time graph' that has acceleration)

2. Amusement Park Physics
Print out the instructions ([|Roller_Coaster.pdf]), and use the link [|HERE] to read about roller coasters, and [|HERE] to build your own roller coaster. Use [|THIS LINK]to view a couple of videos to answer questions #4 and #5. .

3. The "Math" of Acceleration
This will be done in class on Friday, May 9th. See Mr.Hackl for the sheets to complete. .

4. Acceleration/Gravity Video Questions
First, print out the question sheet ([|Acceleration_Gravity_video_questions.pdf]) and then use the link [|HERE] to find the videos to help you out. This will teach more about gravity, weightlessness, and what makes things fall faster, or not at all. .

5. Gravity Problems
This will be done in class on Tuesday, May 13th. Mr.Hackl will give you the sheets to complete then. Here they are ([|gravity.pdf])
