Physics Mousetrap Car – Your Physics Mousetrap Car In Motion

A mousetrap car is a perfect physics example because a student can learn many physics principles in one simple project. For example, a student can learn the force a mousetrap car has. Additionally, you can learn three of Newton’s laws and how those laws of physics apply in the perfect application of your physics mousetrap car.Physics Mousetrap Car - Newton

If this is part of a Science or Physics course, you’ll probably recognize the potential and kinetic energy in a mouse trap car. You will also learn about the centrifugal motion of the wheels, or you may find missing variables by using “kinematics.”

One of the first equations you may use is: F = MA, where you can learn how many newtons (N) a mouse trap car needs in order for the mouse trap car to move at that rate. Also involved in this project is the “mass versus acceleration.” Using the equation F = MA, you can resolve that the smaller the mass equals a faster acceleration.

We can reverse this concept as well where the faster the acceleration may be, the less mass the mousetrap car must have.physics mousetrap car newton image

Physics Mousetrap Car – First Law

Our dear friend Newton stated in his first law that, “everybody continues in its state of rest or uniform motion in a straight line unless it is compelled to change that state by forces impressed on it.” That’s a mouthful, but how it relates to a mouse trap car is that a mouse trap car will not move until a force of the mouse trap car moves it. Eventually, the state of the mouse trap car is bound to change simply because of the forces against it.

In Newton’s second law he stated that: “the acceleration is directly proportional to the force and inversely proportional to mass.” When we apply this principle to the mouse trap car, it means the car will only move when there is an unbalanced force against it. A mouse trap car can change direction and speed because of unbalanced forces at play – a key physics mousetrap car principle.

Physics Mousetrap Car Example

For example, the force of the mouse trap care exceeds the air resistance or pressure at the front of the mouse trap car.

Probably one of Newton’s most often quoted laws, his Third law states: “for every action, there is an equal and opposite reaction.” This is classic for the mouse trap car because in the propulsion forward, the size and force of the air equals the size of the force of the mouse trap car. Because the mouse trap car is moving forward, the direction of the force is backward when the air is pushed back.

In addition to these physics mousetrap car principles, there is also the example of potential energy and kinetic energy. The mouse trap care has potential energy because it is in a stored state until it is released. (The obvious physics mousetrap car principle – but there are more.)

Now when the mouse trap spring is released, the potential energy is converted into kinetic energy with the energy of the moving mouse trap car.

The potential energy is stored in a wound-up mouse trap spring. When the spring is sprung, your mouse trap car has converted it into kinetic energy, which puts that mouse trap car in motion. Bingo, you have just mastered the basic physics mousetrap car power principle!
