Bumper Cars
    Bumper cars are small electric cars with large rubber bumpers all around it that are made to be driven and bumped into other bumper cars in a enclosed space. They are powered by electricity from the ceiling of the enclosed space, which their cars touch with a pole in the back of their car.

Newton's First Law: Law of Inertia
   Newton's first law states that bodies in motion will stay in motion, unless they are acted on by an external force.. So this means if no forces pushing against your bumper car and supposing you didn't step on the gas, you wouldn't move anywhere.

Newton's 2nd Law: Law of Acceleration
     Newton's second law states that the greater the mass of an object, the more its resists being moved, the smaller the acceleration will be.  So in other words; if a obese person would ride the bumper cars, the mass would be ENORMOUS.  If someone of a lighter mass were to hit his bumper car, it wouldn't be moved very far and the acceleration would be a small value.
  It also states that the greater the force applied to an object, the greater the object's acceleration will be.
    This second law gives us an equation:     F=ma.

Newton's 3rd Law: Law of Interaction
    Newton's third law states that for every action there is an equal and opposite reaction.  When a car hits another car, they both will move in opposite directions.  This is because they exert a force on each other when they collide.

Potential & Kinetic Energy
    A bumper car has potential energy when it is at rest, the bumper car has a potential to do work when the rider steps on the gas. When the bumper car is moving, the potential energy is being changed into kinetic energy. To find potential energy and kinetic energy, you can use these equations:
    KE=1/2mv and PE=mgh

Potential energy can be formed for a second car from the kinetic energy of the first bumper car. This potential energy is then once again changed into kinetic energy, but in a second bumper car.
    KEi + PEi = KEf + PEf

Elastic Collisions
    When a collision occurs, forces act on the objects which change the shape or appearance of the bodies. Potential energy is formed from the kinetic energy of the objects. If after the collision, the potential energy becomes kinetic energy once again, this is an elastic collision. Momentum is a mass that has an amount of motion. The more momentum a bumper car has, the harder it is to change it. For the momentum to change there must be a force applied against the bumper car's motion with a certain period of time, which will in turn change the velocity as well.
    momentum=mass*velocity

    Impulse is the change in momentum of an object. Giving us the impulse-momentum theorem, also another way of writing Newton's second law or law of acceleration (F=ma):
    Force * time = mass * velocity
To get this variation of Newton's second law, we had to know one other equation. This equation had to do with finding acceleration:
                 a = v/t

    Conservation of momentum: in collisions where there are no external forces acting on it, the momentum before collision is equal to the momentum after collision. For every action there is an equal and opposite reaction - Newton's 3rd Law (Law of Interaction). The equation this law gives us is:
        mv + MV = mv' + MV'

Conservation of energy: the total amount of energy is always the same if no external forces act on it. The equation this law gives us is:
    1/2mv^2 + 1/2MV^2 = 1/2mv'^2 + 1/2MV'^2
