Mathematics is omnipresent and the significance of it has its mark in every branch of science. Physics is one such area where progress would be unimaginable without the role of mathematics. Predicting the behavior of complex systems…

Life is all about work, but what really does the term work refer to. In physics, work is defined as an activity that involves a force and movement in the direction of the force that is…

Radiant energy is usually carried by the electromagnetic radiation. The S.I. unit of radiant energy is the joule (J) just as is the case with the rest of the forms of energy. The electromagnetic radiation is…

Power can be defined as the time rate of doing work or the amount of work done per second. That is the reason as to why the energy may be equal but if the…

When looking at potential energy you have to consider a force field. The potential energy occurs when an object is situated within the force field. Force Field For there to be potential energy there…
-
Just as the mechanical energy, mechanical power is obtained from a combination of both forces and movement in a mechanical system. Mechanical power can therefore be described as the time derivative of work. The work done…

Mechanical energy is a combination of the potential and kinetic energy. Since potential energy is associated with the position of an object and the kinetic energy is associated with the motion of the object,…
-
Kinetic energy is associated with an object in motion. Mathematically, the kinetic energy of an object in motion is given by: K.E. = ½mv 2 where M is the mass of the object in motion, K.E. is the energy…

Energy is defined as the ability to do work. In short, energy is required for you to accomplish some work. For example, for 100 joules of work to be done, 100 joules of energy…

Electrical energy is derived from the electric potential energy. It is the energy that have been obtained from transforming the electric potential energy. In a more elaborate manner, we can say that electrical energy is…
