Specific heat capacity

When heat is supplied to a material, the particles that make up the material increases the speed of their motion. In a solid, the vibration of the particles becomes faster. In liquid, the particles...

Specific latent heat

Latent heat is the energy involved when matter changes states. There are two types of latent heat: Specific latent heat of fusion This energy is supplied to break the forces between atoms and molecules...

First law of thermodynamics

The first law of thermodynamics can be stated in many different forms. One of the most common form is that energy cannot be created or destroyed, but can change from one form to another....

Work, Energy and Power

Work done Work done by a force is the product of the forces and the distance moved in the direction of the force. SI unit: joule (J) – the SI unit of energy. 1...

Coulomb’s Law

Coulomb’s force is the electrical force between two charges. Since there are positive and negative charges, coulomb’s force can be attractive or repulsive. However, the magnitude of the force produced by a point charge...

Energy of a Simple Harmonic Oscillator

Energy changes in according to displacement The kinetic energy of a simple harmonic oscillator is In a SHM, the oscillator’s kinetic energy and potential energy always changes from maximum to zero throughout the oscillations....

Uniform Gravitational Force

Uniform gravitational force The gravitational force acting on a mass is called weight. Weight always acts vertically down and its magnitude is directly proportional to the mass. where g is the gravitational field strength on...

Centripetal acceleration

For an object moving in a uniform circular motion, the centripetal acceleration is Since  , It is important to note that this centripetal acceleration is not angular acceleration. Angular acceleration is used in a...

The Physics of Simple Harmonic Motion

An object moving in an SHM must obey the relation where  is the displacement and  is the angular frequency of the oscillator.   is related to the frequency of the oscillator by the relation ....
