What is the relation between friction and kinetic energy?

Best Answers

speed^2 = kinetic energy * mass friction = f(speed, …) Speed is a function of the kinetic energy. Friction is a function of the speed and other properties like material, gravity, surface/interface structure etc. read more

Friction is"a force which opposes relative motion" while kinetic energy is the"energy an object has associated with its motion." Frictional work will reduce an object's kinetic energy if it opposes the current speed (ex: a block sliding to rest). read more

Kinetic friction is a non-conservative force, so it must decrease the mechanical energy of a system where friction is present. Static friction does not do work, so it must not affect the mechanical energy of a system. For the third; I cannot imagine a system in which friction points in the direction of motion. read more

The relationship between potential and kinetic energy is that you always use potential energy before you use kinetic energy. Also they are both a type of energy. read more

Lesson: this lesson is about the relationship between potential and kinetic energy. You will learn more about the relation between kinetic and potential energy with our"Energy Skate Park" simulation at the top. 1. Define potential and kinetic energy. Describe the difference between kinetic and potential energy. 2. read more
