How do you find the magnitude of the kinetic frictional force?
Web4 jul. 2024 · Static and Kinetic Friction. Friction is a force resisting relative motion and it occurs at the interface between the bodies, but also within the bodies, like in case of … WebNote, that is is not important how long (in time) the force is exerted. E.g. a cup on a table will feel the constant force due to gravity but is won't move (because the table is pushing … According to the law of conservation of energy, no energy is destroyed due to friction, though it may be lost to the system of concern. Energy is transformed from other forms into thermal energy. A sliding hockey puck comes to rest because friction converts its kinetic energy into heat which raises the thermal energy of the puck and the ice surface. Since heat quickly dissipates, many early philosophers, including Aristotle, wrongly concluded that moving objects lose energy witho… braveheart long hair
