kinetic energy

Under normal conditions matter exists in three forms: solid liquid gas Matter is made up of atoms and molecules. These atoms in molecules are in a state of continuous motion. For example, molecules and atoms of a solid can have only vibrational motion, because they are held in their positions by st..

The kinetic energy, E, of a body moving with a velocity v is given by the equation E = 1 2 m v 2 , where m is the mass of the body. Find the mass of a body moving with a velocity 40 m/s and having an energy of 3000 N. => 4.05 kg or 3.75 kg or 3.65 kg or 6.75 kg..

Kinetic and potential energies that we have so far considered, refer to the object under consideration, as a whole. On the other hand, any given body contains energy because of the motion of the molecules in it. As molecules vibrate with respect to one another, there ..

Wind Energy - Moving air is called wind and it possesses Kinetic energy. In the earlier days, it was utilized by man in winnowing to remove husk from grains, in propelling sail boats in rivers and seas for transport purposes. But nowadays this wind energy is ..

Sunlight falling on the earth's surface equals 50,000 times the energy used each year by man. Almost all our energy comes from sun. The sun's nuclear energy is responsible for the tidal energy, heat energy stored in water, the chemical energy..

Wind energy is one of the first sources of energy known to man. The sun's rays are stronger nearer the equator than in the polar region. This heats the air in equatorial region and warm lighter air rises while cooler polar air moves in to replace it. This movement of air results..

Study the Following Examples: - Water stored in a reservoir is capable of rotating turbines kept at a lower level. Water stored in a reservoir possesses energy by virtue of its position. A nail hit hard with a hammer gets fixed while if the hammer is just placed on the nail, the nail hard..

In this theory, the rate constant is related to three factors Z, f and p by the equation k = Zfp b (19) where Z is the collision frequency f is the fraction of collisions having energy greater than the threshold energy and p is the fraction of the collisions that occurs with the..
