SLANT: Friction and the law of conservation of energy
Sometimes friction makes it look like The Law of Conservation of Energy is being broken.
Friction is a force that resists sliding of two surfaces that are touching.
converts kinetic energy (motion) into thermal energy.
All surfaces have some friction
rough pavement (high friction)
ice (low friction)
friction “wastes” mechanical energy
lubrication (oil) and bearings) reduce friction
make a bike easier to ride
