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 […]

PRESSURE Pressure : Pressure is defined as force acting normally on unit area of the surface. P = F/A = Force/Area SI unit of pressure is N/M2 also called pascal (Pa). Pressure is a Scaler quantity. If the area is less then the pressure will be more. Atmospheric Pressure : It is that pressure which […]
(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 and displacement are in the same direction […]
