## 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.…

## 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…

## 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…

## 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…

## 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…

## 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…

## 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…

## 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…

## Simple Harmonic Motion and Circular Motion

Simple harmonic motion is closely related to a uniform circular motion. A real life simple harmonic motion. Review Question 1 Answer the following questions as you watch the first YouTube video(Simple…
