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 […]
20 Amazing Tricks of Satellite What is Satellite ? Satellite : Satellites are natural or artificial bodies revolving around a planet under its gravitational attraction. 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 = […]
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 […]

40 Amazing Points of Science 10th Class UNIFORM CIRCULAR MOTION (1) If an object moves on a circular path with a constant speed, its motion is said to be a uniform circular motion. (2) In uniform circular motion, the speed of the body remains constant but direction changes continuously, due to which velocity changes continuously. […]
