Electric Cars
+ Currently cost more to buy but
can cost as little as 2-2.5p per mile
to fuel (Next Geencar, 2011)
+ Lower Greenhouse gas emissions
+ Simpler and easier to maintain
BUT
(Next Geencar, 2011)
- National grid wouldn’t cope if we all owned electric cars
- Performance and range is limited by battery technology
- Batteries often require rare materials and contain toxic
substances
- What about the lost tax revenue!
The Challenge
1. Collect data and perform calculations to work
out the minimum range of an electric vehicle.
2. Produce individual posters explaining how
you have approached the problem.
3. Present your poster to members of other
groups.
Things to include on your poster
Your poster must help you explain how your group
attempted the task and could include:
• Write out any formulas you’ve used and include
mathematical working.
• Any graphs of motion you have created using
Easysense (add tangents and data points where you
have used the gradient).
• Sketch diagrams of any experiments you’ve done
• Explain your approach and any assumptions
you’ve made.
