## Measuring the Viscosity of the Liquid

DEFINITION OF VISCOSITY The definition of viscosity is “the quantity that describes a fluid’s resistance to flow. Fluids resist the relative motion of immersed objects through them as well as to the motion of layers with differing velocities within them.” Knowing how thick your material is can have huge impact on your ability to get […]

## SS2 Physics Third Term: LENSES

Topic: LENSES The reflection and refraction we have dealt with so far have focused only on light interacting with flat surfaces. Lenses and curved mirrors are optical instruments designed to focus light in predictable ways. While light striking a curved surface is more complicated than the flat surfaces we have looked at already, the principle

## Classwork Series and Exercises {Physics- SS2}: Equilibrium of Forces

Concept of Equilibrium: Dynamic and Static Equilibrium An object is in equilibrium when it is not accelerated, that is, there is no net force acting on it in any direction. For such a body in equilibrium, the forces acting on it are so related in magnitude and direction that no acceleration results. Thus the body

## Classwork Series and Exercises {Physics- SS1}: Density and Relative Density

Introduction Equal volumes of different substances have different masses or weights. For example 1 m3 of lead weighs differently from 1 m3 of wood. Also 1 m3 of water has a weight different from that of sulphuric acid or palm oil of the same volume. This is due to differences of in the quality of

## If One Screams High Enough, Will One Really Shatter Glass? Science Explains It All

Have you ever heard someone say about a particular singer “She’s got a voice that can break glass”? Or that if you scream in a high-pitched voice long enough in front of a mirror, it will crack? According an explanation by BBC Future, this is actually possible because of a phenomenon known as resonance. When sound

## Classwork Series and Exercises {Physics – SS2}: Glass Prism

Physics SS 3 Week 4 Topic: Glass Prism Spectrum from Prism Sunlight is often called white light, since it is a combination of all the visible colors. Since the index of refraction is different for each color, the angle of refraction will be different for each color when the light passes from air into glass

## Classwork Series and Exercises {Physics – SS3}: Magnetic Field

Physics SS 3 Week 7 Topic: MAGNETIC FIELD INTRODUCTION Magnetic field has a region around a magnet in which the influence of the magnet can be felt or detected. The area around a magnet in which it can attract or repel objects or in which a magnetic force can be detected is called the magnetic

## Classwork Series and Exercises {Physics- SS1}: Projectile and Its Application

Definition of Projectile Motion: A projectile is anybody that is thrown or projected. In other words, a projectile is an object upon which the only force acting is gravity. The projectile motion has two elements: the horizontal projectile motion and the vertical projectile motion. The path of a projectile object and the projectile motion is

## Students Take Note- Best Ways To Study Physics!

Most students are worried about one thing- Physics. This is one of the most difficult subjects to study…well except for the Science Nerds who like to crack their brains! For the regular [average] student though, Physics sure can give quite the headache especially when it’s time for exams! All those complex and varied mathematical problems,

## Classwork Series and Exercises {Physics – SS3}: Electric Field

Physics, SS 3 Week 3 Topic: ELECTRIC FIELD Coulombs Law The electric force between two point charges is directly proportional to the magnitude of each charge (q1, q2), inversely proportional to square of the separation between their centers (r), directed along the separation vector connecting their centers. This relationship is known as Coulomb’s Law. Charles Augustin
