Formula For Kinetic Energy

Formula For Kinetic Energy

Submitted by • September 28, 2012

physics.tutorvista.com - It is a matter of common experience that a fast moving stone can break a windowpane, falling water can rotate turbines and moving air can rotate windmills and propel sailboats. In all these examples, the moving body possesses energy. Work ...

Examples Of Potential Energy

Examples Of Potential Energy

Submitted by • September 26, 2012

physics.tutorvista.com - Let us throw a ball up and it falls after reaching a certain height. We have given kinetic energy to throw the ball, so where does its energy go when it will reach its maximum height? It's been converted into ...

Centripetal Force Equation

Centripetal Force Equation

Submitted by • September 17, 2012

physics.tutorvista.com - Sir Isaac Newton discovered that every particle attracts every another particle in the universe with a force when he saw an apple fell from a tree towards the earth. The force of attraction between any two particles in the universe ...

Law Of Thermodynamics

Law Of Thermodynamics

Submitted by • August 16, 2012

physics.tutorvista.com - Thermodynamics is a macroscopic science which studies various energy inter-actions, notably heat and work transfer, with matter, that brings about significant changes in the macroscopic properties of a substance that are measurable. It is basically a phenomenological science based on ...

Equation For Velocity

Equation For Velocity

Submitted by • August 3, 2012

physics.tutorvista.com - Speed and velocity, these terms gives us an idea of how slow or how fast a body is moving. Quite a few times, we need to know which one of the two or more objects is moving faster. One can ...

Enthalpy Of Vaporization

Enthalpy Of Vaporization

Submitted by • August 1, 2012

physics.tutorvista.com - There is one irony the enthalpy is not measurable directly rather the change in enthalpy is important. Change in enthalpy is sometimes equal to the heat energy that is absorbed or released by the system during a reaction. Enthalpy basically simplifies ...

Electrical Resistance

Electrical Resistance

Submitted by • July 31, 2012

physics.tutorvista.com - Components in a circuit make it harder for an electric current to flow. One light bulb connected in a serious circuit would glow brightly, two light bulb would be dimmer, and three are dimmer still. The more light bulbs there ...
