How to build the Mouse Trap
Car
Goals & Objectives
●
● To demonstrate how there are alternative
ways besides fuel and power sources to
make vehicles move
● To leave with a functional moving car
● To be able to explain how the car works
Energy, Motion and Friction
● Energy:
● What is energy?
● From where we have energy
● Is our cart in need of a source of energy to work?
● Motion
● What is motion?
● Transforming energy to move the cart
Energy, Motion and Friction
● Friction
● What is friction
● Transforming energy into heat
● Not all the friction is negative
● How does friction affect the motion of a
vehicle?
● Without friction our cart can not move
● The friction convert energy that can be use to move
the cart into heat that we do not need!!!
What is a turbo mousetrap cart and
how does it work?
● A turbo mousetrap cart is a vehicle that is
powered by the energy of a wound-up
mousetrap spring.
● The string is wound around the axle by the
turning of the wheels, the snappper’s lever
arm is pulled close to the drive axle causing
the mouse trap's “wind-up” and store
energy. When the string is released the
drive axle by the mousetrap will cause the
wheels to rotate.
