*Smash-Up Derby Cars -childrens toy.
*Speciality:
A flywheel is, quite simply, any rotating disk installed to collect and supply energy to a given system by storing this energy in the form of rotational Kinetic Energy.
*In application of flywheels in vehicles, the phenomenon of precession has to be considered. A rotating flywheel responds to any momentum that tends to change the direction of its axis of rotation by a resulting precession rotation. A vehicle with a vertical-axis flywheel would experience a lateral momentum when passing the top of a hill or the bottom of a valley (roll momentum in response to a pitch change). Two counter-rotating flywheels may be needed to eliminate this effect.
A momentum wheel is a type of flywheel useful in satellite pointing operations, in which the flywheels are used to point the satellite's instruments in the correct directions without the use of thrusters.
The flywheel has been used since ancient times, the most common traditional example being the potter's wheel. In the Industrial Revolution, James Watt contributed to the development of the flywheel in the steam engine, and his contemporary James Pickard used a flywheel combined with a crank to transform reciprocating into rotary motion.

*A flywheel is a rotating disk used as a storage device for kinetic energy. Flywheels resist changes in their rotational speed, which helps steady the rotation of the shaft when a fluctuating torque is exerted on it by its power source such as a piston-based (reciprocating) engine, or when the load placed on it is intermittent (such as a piston pump). Flywheels can be used to produce very high power pulses as needed for some experiments, where drawing the power from the public network would produce unacceptable spikes. A small motor can accelerate the flywheel between the pulses. Recently, flywheels have become the subject of extensive research as power storage devices for uses in vehicles; see flywheel energy storage. Flywheel drive is common in low-cost toys.

A flywheel is a cicular disk with lots of weight, prefferably on the outside rim. As it spins, it has two distinct effects. The first is that it does not stop easily and the second is that it has immaculate balance. Any possible toy you can imagine that goes by itself without batteries after you let it go can possibly have some sort of flywheel. Cars, and motorbikes, helicopters ornthopters, tops if it has something that goes around and it seems to have good balance. You can expect a flywheel. Flywheels are always used in heavy reciprocating machinary (machines that go up and down) where there is a revolving axle. The flywheel in this case keeps the "engine" running smoothly while the "pistons" move ruggedly up and down. (The best example of this is your car engine.)

Most satellites carry reaction wheels that allow for changing the attitude (direction of pointing) of the satellite without use of small rocket engines (which use valuable fuel). Flywheels spin, and if they change their angular momentum (by use of electric motors) torque is developed and the body of the satellite responds by rotating.

With 3 flywheels in 3 orthogonal axes it is possible to point the satellite in any direction in space.

The flywheel attached to the engine in an RC car lessens the shock transmitted to the engine when the wheels encounter abrupt resistance, such as when you crash it into a wall. It also helps add momentum to the car's velocity without actually adding forward speed.

gyroscope toys are flywheels.
Friction drive cars that you push along the floor quickly (while saying vroom vroom) to wind up the internal flywheel then the car drives itself the across floor and down the steps
A top
The flywheel stores kinetic energy, they can self balance
