The greenhouse effect and global warming

A greenhouse is a small glass building that is used for growing plants to protect them from the cold. Understanding how it works to trap heat can help you to understand global warming because the principles are the same. Two key things to… Continue Reading →

Convection

Convection is the flow of heat in a liquid or gas from a region of high temperature to a region of lower temperature where the whole medium moves and carries heat energy with it. It is caused by a change in… Continue Reading →

Radiation

Radiation occurs when heat transfers from a high temperature region to a lower temperature region without the movement of particles. Therefore radiation can travel though a vacuum, i.e. it does not need a physical medium such as a liquid or… Continue Reading →

Conduction

When heat moves from a region of high temperature to a region of low temperature without the molecules actually moving from one place to another, this is called conduction.  Molecules only vibrate about their average position, they don’t move from place… Continue Reading →

Galileo’s Contribution to Science

Galileo Galilei, born in Italy in 1564 made contributions to Physics and Astronomy and has been called the father of science. He is well known for developing the approach to the scientific theory. His method of careful experimentation and observation… Continue Reading →

Density

This is a question of density. Which of these two blocks would be heavier? One is made of lead and the other is made of cork (that’s the same cork that is used to seal wine bottles.) The Explanation Density… Continue Reading →

Mass and Weight

It is common for students to mix up the terms mass and weight when studying physics.  Mostly it is because people generally have experiences with it before starting to study. We usually talk about how much we weigh or about how much this sack… Continue Reading →

Difference between scalars and vectors

What is a vector or a scalar quantity? To help you to understand a little bit about scalar and vector quantities, imagine this scenario. You want some juice to drink, so you ask your sibling if there is any in… Continue Reading →

Center of gravity

The center of gravity (center of mass), is the point at which the whole weight of a body is considered to act. How to find the center of gravity for irregular objects Activity Here is an activity to determine the center of… Continue Reading →

Investigate the effect of length on the period of a simple pendulum

This is a simple pendulum experiment. It is a simulation and therefore is a lot easier to carry out than the live experiment. Use it to verify your values for the period of a pendulum for a specific length. The… Continue Reading →
