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. […]
Force 30 Amazing Science Points with Force (1) Force is an external effort in the form of push or pull which changes the state of rest or of uniform motion of a body along a straight line. (2) Forces may be classified into two types…..(A) Contact Forces (B) Non – contact forces (3) Contact force […]

Learn Science With Executive Makers [GS] [Science] Law of Floatation, Buoyant Force, Archimedes Principle, Density & Relative Density 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 […]
