Kinetic energy or the energy of motion is used which is then transformed to heat energy.
Friction is NOT energy. Friction is a FORCE (rather than a form of energy). It can be used in the formula: W = F·d where "W" stands for work (which IS energy), F stands for force (like friction), and "d" stands for distance over which the force is exerted. Typically when friction is present some kind of energy of motion such as mechanical energy or kinetic energy or potential energy is being transformed into heat.
energy
heat/thermal
Mechanical energy is used, and thermal energy is produced
friction, heat, kinematic
When mechanical energy is lost due to friction, it is converted into thermal energy, also known as heat energy. This occurs because the friction between surfaces causes the molecules to vibrate and create heat.
The friction produced by rubbing your hands together is kinetic friction, which occurs when two objects are moving relative to one another. This type of friction converts kinetic energy into heat energy.
The energy used to overcome friction is converted into heat. Friction converts mechanical energy into thermal energy as objects slide or rub against each other. This heat energy dissipates into the surrounding environment.
Friction is good because it provides traction. Friction is necessary for people to stand, or for vehicles to accelerate or break. Friction can also be used to convert kinetic energy to heat or electrical energy. Friction can be bad because kinetic energy is can be lost to friction.
When you light a match, chemical energy is transformed to thermal energy, primarily by oxidation. When you actually strike it, the triggering energy is mechanical energy that creates heat through friction to begin the oxidation process (combustion).
That one kind thats really hot sometimes
When you apply the brakes, you are experiencing kinetic friction between the brake pads and the brake rotors. This friction converts the kinetic energy of the moving vehicle into thermal energy, which helps slow down the vehicle.
