Mousetrap report.
The mouse trap racer provides an excellent demonstration of energy conversion and structural strength through triangulation.

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
