To build a successful mouse trap racer in physics class, start with a sturdy base that can support the mouse trap and wheels, using materials like wood or cardboard. Opt for large, lightweight wheels that roll smoothly to enhance performance. The strength of the mouse trap is crucial, so select a powerful one to maximize distance. Experimenting with various designs can lead to better results, and lightweight materials like balsa wood or plastic will help increase speed. Testing and making adjustments before the final race is essential for achieving the best performance.

You want really big back wheels, a thin axle and a long arm.
 


Hi there! Building a mouse trap racer can be a fun and challenging project in physics class. Here are some tips to help you build a winning racer:

1. Start with a sturdy base: The base of your racer should be strong enough to support the weight of the mouse trap and the wheels. You can use a piece of wood or a sturdy cardboard for the base.

2. Choose the right wheels: The size and type of wheels can greatly affect the performance of your racer. Make sure to choose lightweight and smooth wheels that will roll easily.

3. Use a powerful mouse trap: The strength of your mouse trap will determine how far your racer can go. Look for a powerful mouse trap that can generate a lot of force.

4. Experiment with different designs: There are many different designs for mouse trap racers, so don't be afraid to experiment and try different designs. You can also look for inspiration online or ask your teacher for ideas.

5. Keep it lightweight: The lighter your racer is, the faster it will go. Try to use lightweight materials for your racer, such as balsa wood or plastic.

Remember to always test your racer before the final race and make adjustments as needed. Good luck and have fun building your winning mouse trap racer!
 
Thread 'Correct statement about size of wire to produce larger extension'
The answer is (B) but I don't really understand why. Based on formula of Young Modulus: $$x=\frac{FL}{AE}$$ The second wire made of the same material so it means they have same Young Modulus. Larger extension means larger value of ##x## so to get larger value of ##x## we can increase ##F## and ##L## and decrease ##A## I am not sure whether there is change in ##F## for first and second wire so I will just assume ##F## does not change. It leaves (B) and (C) as possible options so why is (C)...
