Mechanical energy is changed into heat energy, The temperature of objects increases by increasing their speed due to the increase of their kinetic energy, You feel warm when you rub your hands together in...
At the maximum height of a projectile, its mechanical energy is equal to its potential energy only because the mechanical energy of an object is the sum of potential and kinetic energies of the...
Energy is the ability to do work or to make a change, The measuring unit of energy is the joule, We need energy in different fields in our life, We provide cars with fuel...
Alternating current generator is a device that converts mechanical energy into electric energy, When the coil rotates between the two poles of the magnet, it intercepts the magnetic flux lines which generate the induced...
