 ## Chapter 2 – Kinematics

1. A car travels round a circular track at a constant speed of 40 km/h. Explain why the car’s velocity is not constant Velocity is a vector quantity that depends on both direction and magnitude. Since the car’s direction changes continuously as it travels around a circular track, its velocity changes all the time. Is …

## Chapter 1 – Measurements

1. Describe an experiment to show how the period of pendulum can be determined The simple pendulum is made to oscillate at a small angle. When the oscillation is steady, the time taken for 20 oscillations is measured using a stopwatch. The measurement is repeated and the average is calculated. The period of the pendulum …

## Famous Physicist – Albert Einstein

Albert Einstein is probably the most famous and iconic scientist who have changed the world and what we think about the universe. Born in 1879 in Germany and lived for 76 years (died in 1955), he was a scientist who specialized in Physics. He is also known as a theoretical physicist (a scientist who try …

## Physics and Climate Change

Climate can be described as the sum of the weather. Weather and climate are driven by the absorption of solar radiation and the subsequent re-distribution of that energy through radiative, advective, and hydrological processes.  Did you know that scientists understood the physics of climate change in the 1800s? This was discovered by an American female …

## Physics in the Bedroom

Alarm clock The ringing of your alarm clock helps you get up in the morning and get ready for school. Sound is something that we cannot see with our visible eyes but can be experienced. Sound waves travel from the alarm clock and works on the concept of Quantum Mechanics and Quantum Physics, which involves the origin, …
