SPH4C: THE GREAT PHYSICS CART CONTEST!
Your task is to design a car-like device that will roll along the school hallway when released from rest.
1. Each cart will have three trials for judging.
2. The carts will compete in at least one of the following categories (you choose)
a) Fastest (shortest time for a 5 m race)
b) Furthest distance
c) Stop on a line at a designated distance of 3 m away
1. The cart must fit in your locker.
2. It must have a minimum of three wheels.
3. The cart must be made of recycled or reused materials and not from pre-made toy cars
4. The cart must be powered by elastic bands.
5. The cart must start on its own when released from a stationary position.
This project may be done individually or with a partner (1). If this project is done as a pair, your group must complete the group work form on the back of this page.
Performance Analysis Report:
Your performance analysis report will include:Your initial plan for your vehicle, including a list of materials and an initial drawing
A drawing of your final vehicle, including a list of materials
A position-time graph for your cart based on the data you take using a ticker-tape timer
From your graph, determine your cart's instantaneous speed at a point approximately half-way through its motion
Time your car and give its average velocity for a 1 m trip, a 2 m trip and a 3 m trip.
A reflection on how your vehicle did on the day of the contest and deas on what could be changed to improve the performance of your vehicle if you were to enter another contest
To brag about your car you must make a full page advertisement (8.5 x 11" in size) that shows your car and mentions at least one exciting competition result or piece of analysis.
Build your car as soon as you can!! Three class periods are scheduled to conduct your analysis. Your cart will be handed in on the competition day. Your report and advertisement will be due the day after the competition.
