Dodgems Cars.

Remember the Dodgems on a Saturday night, drunken aussie clowns whizzing around pretending to be top racing car drivers.
The girls helped of course and what about those tall pimply faced lads who jumped and whirled around on the back of the cars showing off and pretending to help people! Dickheads.
But did you know that Newton’s third law of motion comes into play on the Dodgems. It’s the law of action and reaction, and it helps to explain why you feel a jolt when you collide with another dodgem car.
Dodgem car rides are designed so that the cars can collide without much danger to the riders.
Each car has a large rubber bumper all around it, which prolongs the impact and diffuses the force of the collision. But, why they called them Dodgems beats me!
The Dodgems run on electricity, carried by a pole on the back of the car that leads up to a wire grid in the ride’s ceiling. This grid carries the electricity that runs the car.
Electrical energy carried to the cars from the grid is converted to kinetic energy, some of which is converted to heat.

When dodgem cars collide, the drivers feel a change in their motion and become aware of their inertia. Though the cars themselves may stop or change direction, the drivers continue in the direction they were moving before the collision.
The weight of the drivers also affect the collisions.
A difference in weight between two dodgem car riders will mean that one rider experiences more change in motion than the other (or more of a jolt). The type of collision, velocity of the cars, and mass of the individual drivers all come into play in dodgem car collisions.
So there, now you know.
