VISCOSITY
MEANING OF VISCOSITY Viscosity is the internal friction which exists between layers of the molecules of a fluid (liquid or gas) in motion. The viscosity of a fluid can also be defined as the measure of how resistive the fluid…

WORK, ENERGY AND POWER
WORK Work is said to be done whenever a force moves a body through a certain distance in the direction of force. Work done can be defined mathematically as the product of the force and the displacement. It is a…
PRESSURE, ARCHIMEDES’ PRINCIPLES, UPTHRUST & LAWS OF FLOATATION
PRESSURE Pressure is defined as the perpendicular force per unit area acting on a surface. It is a scalar quantity & measured in N/m2 or Pascal (pa).It can also be defined as the force per unit area, which is calculated…
DENSITY & RELATIVE DENSITY
DEFINITION OF DENSITY The density of a substance is the mass per unit volume of the substance. Density = mass of a given substance Volume of the substance Density is scalar quantity& measured in kgm-3 (kilogram per cubic meter) …

VECTOR & SCALAR QUANTITY, DISTANCE/DISPLACEMENT, SPEED/VELOCITY, ACCELERATION, DISTANCE/DISPLACEMENT –TIME GRAPH, SPEED/VELOCITY–TIME GRAPH SCALAR & VECTOR QUANTITY A scalar quantity is defined as a quantity that has magnitude only but no direction. Typical examples of scalar quantities are time, distance, speed,…
FRICTION
DEFINITION OF FRICTION Friction (Fr) is defined as a force which acts at the surface of separation between two objects or two bodies in contact and tend to oppose the motion of one over the other. It is simply force…
MOTION IN NATURE
FUNDAMENTALS OF MOTION Many scientists have studied motion and its properties because of its importance to life. The Italian, Galileo Galilei, who lived from 1564 to 1642, did the first systematic study of motion. The science of the study of…
MEASUREMENT OF MASS, WEIGHT, LENGTH & TIME
TECHNIQUES AND MEASUREMENT Measurement is an important aspect of physics or other sciences. No fact in science is accepted, no law is established, unless it can be exactly measured and quantified. As physics is based on exact measurements, every such…
INTRODUCTION TO PHYSICS
MEANING OF PHYSICS Physics is the scientific study of matter and energy and how they interact with each other. This energy can take the form of motion, light, electricity, radiation, gravity etc. Physics deals with matter on scales ranging from…
