Centripetal force and centrifugal force, action-reaction force pair associated with a circular motion. Some geographers realized that just as different forces can pull things apart…

Heat and temperature are two different quantities. The essential difference between heat and temperature is that Heat is that the variety of energy that transfers…

Reflection usually begins with an outline of what went on. Common examples include the reflection of sunshine, sound, and water waves. The law of reflection…

When an object is moving, the friction is proportional and perpendicular to the normal force (N). Friction is independent of the area of contact as…

An image that can be formed on the screen is known as a real image and the one which cannot be formed on the screen…

Poisson’s Ratio ν(nu) is a measure of the Poisson effect, and it is the ratio of transverse strain to corresponding axial strain on a material…

Thermodynamics is a branch of physics; it deals with the transfer of energy from one place to another and from one form to another. The…

Clouds are usually grouped into different types based on their altitude (how high they are in the sky) and their shape. There are ten cloud…

In physics and engineering, fluid dynamics is a subdiscipline of fluid mechanics that describes the flow of fluids—liquids and gases. It is the branch of…

Definition of Rotation – For much of human history, people believed Earth to be flat. We now know better. But if Earth were flat, the…

Potatoes have phosphoric acid and work well; they are the basis for commercial “potato clock” kits. Potato batteries with LED lighting have been proposed for…

Electricity is everywhere in our lives. From the voltage that comes from the wall to power our lights, to the batteries in our phones and…
