The force is 'trying' to move the surfaces in relation to each other. Does it succeed?paalfis said:Linear integral of scalar product between force and the direction of motion. But does THIS force does any work? Because after all, it is static, but its point of action is changing with time, that is my confusion.
Correct.paalfis said:Energy won't be conserved if there is any slipping between the surfaces, correct?
There is some truth in that. In the case of a rolling wheel, there are losses associated with the deformation of the road and wheel as the load shifts. But this is referred to as rolling resistance, not friction. It is generally ignored in 'school', in the same way that air drag is ignored in most ballistics questions.paalfis said:I think static force as 'pressure' applied by each body to the other body, somehow using energy to change the molecular state of the other body's structure
Conservation of energy in a wheel is a physical principle that states that the total amount of energy in a system remains constant, even as it undergoes various transformations. In the case of a wheel, energy can be conserved through its rotational motion.
A wheel conserves energy through its rotational motion. As the wheel turns, kinetic energy is transferred from the axle to the rim of the wheel, keeping the total amount of energy in the system constant.
Conservation of energy is important in a wheel because it allows the wheel to continue rotating without slowing down or stopping due to friction or other external forces. This makes it an efficient mechanism for transportation and other mechanical systems.
The conservation of energy in a wheel can be affected by factors such as the mass and shape of the wheel, the surface it is rolling on, and the amount of friction present in the system. These factors can impact the amount of energy transferred and the efficiency of the wheel.
Conservation of energy in a wheel is related to other laws of physics, such as the law of inertia and the laws of motion. These laws explain how the wheel maintains its rotational motion and how the energy is conserved despite external forces acting on the system.
