Unless a brake is engaged, the wheels on a car in neutral can rotate backwards. If the car is in gear, wheels attached to the power train probably will only rotate backwards if the car is in reverse gear. If it is in forward gear or "park" they should not rotate backwards. Wheels not connected to the power train should be able to rotate either direction.
no its a grooved wheel with a rope running along the groove the above answer is wrong because it is the definition of a pulley. Yes that is true. A wheel and axle is a simple machine consisting of two wheels of different sizes that rotate together.
A car wheel is attached to an axle. If the car is RWD, the rear wheel axle will be connected to the engine and the front wheels not be. In a 4WD or FWD car the front axle, with a ball joint to allow steering, will also be connected to the engine via a torque tube and a geared differential.
They rotate and can be braked, just like auto wheels. Nose wheels can be steered.
Cars have circular wheels to move the easiest. Because of the circle's shape, the wheels can rotate easily. If they were not circles, it would take a great amount of work and energy to get the wheel to rotate.
An axle is attached to the center of wheels.
Usually the back wheels are the ones connected to the engine, providing the power to rotate the tracks, and these are the drive wheels. The rest are bogey wheels.
