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...
Converting the mass (m) into energy (E) is related to the Einstein relation (E = mc²) which is the scientific base of the nuclear bomb where it was found that the fission of the...
Some electric circuits consist of many branches and are too complicated to be managed by Ohm’s law because the electric current passing through them is different in each branch, For such cases, a German...
The energy is the capacity to do work , There are different forms of energy that can be converted into one another , Such as in the waterfall , The potential energy is converted...
