In the previous essay we have discussed about relative motion where Mr. A was chasing a car. Mr. A, moving at 3 km/h (w.r.t. reference), found the car’s speed is 7 km/h when the car was…

Place yourself in a moving car, when you see the person next to you, he appears to be at rest, but for someone standing on the footpath the same person appears to be moving at certain…

Electrical heating appliances like heaters and geysers are some of the luxuries offered by science. All of us use them in daily life and a day without these appliances is a nightmare in the cold countries…

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,…
