1. Pls tell me the direction of friction on the rear wheel of a cycle moving down on an incline plane in both the cases that are when cycle is being paddled and without any paddling ?

when pedalling in forward and when not pedalling in backwardChestermiller said:What is your answer to this question if there is no incline?
"Friction" or "rolling resistance" for the non-driving tires? There is some friction force at the axles of the non-driving wheels (but that is effectively a small amont of braking), which will also mean some friction force at the tires.tiny-tim said:"In particular, the friction from the road on the driving or braking wheels of a car is in the same direction as the acceleration or braking, but the friction on the non-driving or non-braking wheels of a car is in the opposite direction."
Rear wheel friction refers to the resistance or force that occurs between the rear wheel of a bicycle and the surface it is moving on. This friction is caused by the contact between the tire and the ground, and can affect the speed and efficiency of cycling.
Rear wheel friction plays a crucial role in cycling on an incline. As the incline increases, the force of gravity pulling the cyclist and the bike downhill also increases. This means that the rear wheel has to work harder to maintain traction and move the bike forward, resulting in increased friction and a decrease in speed.
The main factors that can affect rear wheel friction include the type and condition of the tire, the surface being cycled on (e.g. pavement, gravel, dirt), the weight of the rider and the bike, and the angle of the incline. Additionally, weather conditions such as wet or icy surfaces can also impact rear wheel friction.
To reduce rear wheel friction while cycling on an incline, it is important to ensure that the bike and its components are well-maintained, including regularly checking and inflating tires, and keeping the chain lubricated. Choosing a bike with wider tires and a lower gear ratio can also help to reduce friction. Proper cycling technique, such as distributing body weight evenly and pedaling smoothly, can also help to minimize rear wheel friction.
Rear wheel friction can be measured using a dynamometer, which is a device that measures the force needed to rotate a wheel. This can help to determine the amount of resistance and friction being experienced while cycling on an incline, and can be used to compare different tires and surfaces. Another way to measure rear wheel friction is by using a power meter, which can calculate the power output of the cyclist and provide information about the efficiency of cycling on an incline.
