 Measuring Length Using Vernier Callipers -Vernier callipers is used when higher accuracy in measurement is required and this cannot be done using a metre rule.– Vernier callipers has two scales; main scale and vernier scale. Outside jaws are used to measure both…

Magnetism: Introduction – Magnets are substances that are able to attract and hold items. Magnets and Non-Magnetic Materials – Magnetic materials are those that are strongly attracted by magnets while non-magnetic ones are those that are not affected by magnets.–…

Introduction to Pressure – It is defined as the force acting normally (perpendicularly) per unit area– The SI units for pressure is newton per metre squared (N/m² or Nm-2). – One Nm-2 is known as one Pascal (Pa). Formula for Pressure – pressure is…

Measurement comprises of length, area, volume, mass, density and time. Universal System of Units is called system international d’ unites (International System of Units) – SI Units.Below are the major SI Units Basic Quantity SI Unit Symbol Length Metre m Mass Kilogram…

Physics is a Greek word meaning nature hence it deals with natural phenomena. What is Physics? – Physics is therefore a science whose objective is the study of components of matter and their mutual interactions.– Physics is also defined as the…
