The key to making a mouse trap car move faster is reducing friction and increasing the force applied to the wheels. This can be done by using smoother materials for the wheels, reducing the weight of the car, and adjusting the position of the mouse trap to maximize the pulling force.
To improve the distance of your mouse trap car, you can make sure the wheels are aligned properly and that there is minimal friction on the axles. You can also try using a longer lever arm for the mouse trap, as this will increase the pulling force and therefore the distance traveled.
The best design for a mouse trap car will depend on your goals and resources. However, a lightweight and aerodynamic design with smooth wheels, a long lever arm, and minimal friction on the axles tends to work well for speed and distance.
The force and speed of a mouse trap car can be calculated using basic physics equations. The pulling force can be calculated by measuring the distance the mouse trap arm moves and the spring constant of the trap. The speed can be calculated by dividing the distance traveled by the time it took to travel that distance.
Some common mistakes to avoid when building a mouse trap car include using heavy materials, not properly aligning the wheels, and having too much friction on the axles. It is also important to make sure the lever arm is securely attached to the axle and that the mouse trap is set up properly for maximum pulling force.
