One of the examples is vehicles are designed in "AERO DYNAMIC" model.
Lubrication and/or bearings, of various types, were the new techniques adopted by human beings to reduce energy loss due to friction.
No, energy transfer is not the same as friction.
The form of energy generated by friction is called mechanical energy. Friction between surfaces can convert mechanical energy into heat energy.
The human body creates synovial fluid, which is found in our joints. This is a lubricating fluid, which reduces friction. When a joint loses its synovial fluid, bones can touch each other, which causes joint pain. This can be alleviated medically by having a series of joint injections with an artificial synovial fluid called hyaluronic acid. There are two common supplements, which are also used to reduce joint friction, glucosamine and chondroitin.
Friction produces thermal energy, also known as heat energy. This is because as objects rub against each other, the kinetic energy of their movement is converted into heat energy due to the resistance of friction between the surfaces.
Friction causes kinetic energy to be converted into heat energy.
Friction causes mechanical energy to be transformed into heat energy.
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.
Friction does not necessarily cause mechanical energy to be transformed into potential energy. Friction typically results in the conversion of mechanical energy into thermal energy, leading to an increase in temperature in the objects experiencing friction. Potential energy is associated with the position of an object in a gravitational field or an elastic material, and it is not directly influenced by friction.
Friction converts kinetic energy to thermal energy, causing the surfaces in contact to heat up. The energy lost to friction results in a decrease in the overall kinetic energy of the system.
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.
Friction converts kinetic energy into thermal energy as objects rub against each other. Although some energy is lost in the form of heat due to friction, energy is not actually destroyed. It simply changes form from mechanical energy to thermal energy.
