To reduce friction
the chain and axle(s)
In general rolling friction is any friction specifically related to the rolling motion. The friction on the axle to hub bearing, the tire flexing, the tire tread on the surface of the road and so on.
If the push is light enough, you do not provide enough force to overcome the inertia of the axle and the static/rolling friction of the axle.

Well.. There is surface friction from the tires on the road, there is air friction from the bike itself ,, more air surface friction if your on it.. Then there is mechanical friction through the resistance of the, chain, bearing assembly grease in axle.
A friction bearing is a solid bearing that directly supports the end of an axle. Friction is when the bearing and the joint are running together.
The purpose of a wheel and axle is to reduce the total friction that acts against the linear motion of an object along a surface.
wheel is a type of circle which is used in vehicles etc. and axle in science means which is related to wheel. like friction is needed so that wheels could turn about the axle.
They are aerodynamic drag and the friction between (a) the go-cart and the track, and between the axle and axle-mounts of the cart.
THE ROLLING ITEM THAT MAKES CONTACT WITH THE FRICTION SURFACE [WHEEL] THE THE DEVICE THAT TRANSMIT THE FORCE FROM THE POWER UNIT TO THE WHEEL. [AXLE]
Yes Friction between the wheels and the ramp and also friction between the body of the car and the air (unless the car and ramp are in a perfect vacuum) There will be additional friction in the bearings or ball race of the wheel / axle too
