Friction can create heat and help us make campfires, lighting up a match. dat are the good part of friction. Friction provides required energy, converts from mechanical to other form of useful energy. ... 3 No two bodies will stick to each other if there is no friction.

Endothermic and exothermic reactions are chemical reactions that absorb and release heat, respectively. A good example of an endothermic reaction is photosynthesis. Combustion is an example of an exothermic reaction. ... In any given reaction, heat is both absorbed and released.

Friction is a force that resists the relative motion between two objects or materials. The causes of this resistive force are molecular adhesion, surface roughness, and deformations. ... But surface roughness is a factor when the materials are rough enough to cause serious abrasion. This is called the sandpaper effect.

One natural example of convection currents is wind. As the Sun shines down on an area of land, it heats the air above the ground. That warm air rises. As it rises, cooler air moves in to take the place at the bottom.

No. It can not exist. Static or sliding frictions are always there acting on the object. Frictional force and the applied force are always in opposite direction.

Some examples include hydropower, solar, wind, tidal, geothermal energy from inside the earth, biomass from plants, and nuclear fusion. These types of energy sources are usually converted into electricity or thermal (heat) energy.

1 Answer. For the force of gravity use F=ma where a is the acceleration of gravity. For the frictional force, multiply this F by the coefficient to get Ff=μF=0.105F. For the thermal energy use W=Ffd, where W is the work and d is the distance.

I know that friction is the resistance to motion that occurs between objects. So friction is a force that work opposite the direction you rub an object against another object. ... If the friction is negative then the direction will be the same as you rub an object against another object.

Examples of matter containing chemical energy include: Coal: Combustion reaction converts chemical energy into light and heat. Wood: Combustion reaction converts chemical energy into light and heat. Petroleum: Can be burned to release light and heat or changed into another form of chemical energy, such as gasoline.

Friction produces static electricity by initiating the transfer of electrons between two or more objects. With regards to electron transfers, objects are either conductors or insulators. Conductors give up electrons readily because the electrons are not confined to a particular atom.
