Heading - Mouse trap racer.
Aim - To construct a vehicle that propels itself as far as possible powered by a mouse trap.
Design - Draw a design of
your mouse trap racer. Take into consideration and discuss the following:
-Where frictional forces are
acting on the mouse trap racer and the ways in which you have attempted
to reduce these forces.
-Ways of getting the vehicle
to travel as far as possible through the action of a single release
of the mouse trap spring.
-The reason behind your selection of the type of wheels and their size.
-The reason behind the use of an extension arm attached to the spring.
6 marks
Discuss -
The type of energy conversion occurring when the mouse trap spring is
released.
How can the spring be made to store more energy?
2 marks
Evaluation-
How far did your mouse trap
racer travel?
What was the average speed of your mousetrap in metres per second?
What modifications can you make to the design in order to improve its
performance?
Does adding weight to your vehicle make it go further? Explain
1 + 2 + 5+
2 = 10 marks
Conclusion - My mousetrap traveled ______ m/s
Total marks possible 18.
Calculate the displacement of the mouse trap racer.
2 marks
Calculate the speed of the racer during:
- the first 10 seconds?
- 17 and 21 seconds into the run.
2 marks
What is the average speed of the racer over the 22 second race?
2 marks
What is the acceleration of the racer from 6 to 10 seconds?
What is the acceleration of the racer from 18 to 21 seconds?
What is the distance covered by the racer in the first 10 seconds?
What is the total distance the racer covers over the entire 22 second race?
Has the racer stopped 15 seconds into the race? Explain
