20 Amazing Tricks of Archimedes Principle 20 Amazing Tricks of Archimedes Principle Floatation: Buoyant Force: When a body is immersed partly or wholly in a liquid, a force acts on the body by the liquid in the upward direction. This force is called buoyant force or upthrust. It is equal to the weight of liquid […]

Moon is a natural satellite while INSAT-IB is an artificial satellite of earth. 20 Amazing Tricks of Satellite Orbital speed of a satellite : Orbital speed of a satellite is […]
20 Amazing Tricks of Gravitation GRAVITATION Gravitation : Every body attracts other body by a force called force of gravitation. Newton’s law of Gravitation : The force of gravitational attraction between two bodies is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. F = […]
30 Amazing Tricks of Surface Tension SURFACE TENSION Surface Tension : It is the property of a liquid by virtue of which it has the tendency to have the area of its free surface minimum as if it were under tension like a stretched elastic membrane. If a force F acts on an imaginary line […]
20 Amazing Tricks of Pressure in Science Pressure: Pressure is defined as force acting normally on unit area of the surface. P = F/A [ Normal Force on the Surface / Area of the Surface] SI unit of pressure is N/M2 also called pascal (Pa).Pressure is a scaler quantity. If the area is less then […]
30 Amazing Tricks of Work and Power (Work Power and Energy) Work: If a body gets displaced when a force acts on it, work is said to be done. Work is measured by the product of force and displacement of the body along the direction of force. W = F S cosθ If both force […]
