Class 9th – KINETIC ENERGY
Any object that is having the capability to do work possesses energy. The energy possessed by a moving object is called Kinetic Energy. The energy can be transferred from one form to another, i.e. an object S does the work on object K, if an object S which does the work looses energy and the…

Class 9th – WORK
Work is defined as the force acting upon an object that causes an object to move. It is defined as the product of the magnitude of force and the displacement due to force. W=F x s Here, W= work done on an object F = Force on the object s = Displacement of the object Work done depends upon 2 factors…

Class 9th – Gravitation – THRUST & PRESSURE
THRUST The force that is applied on a surface that is perpendicular to the surface is called THRUST. Thus thrust is a perpendicular force. Its SI Unit is N (Newton) Thrust is in opposite direction to gravity. PRESSURE Thrust on unit area is called Pressure. When Force F is applied on a Surface Area A…

Class 9th – GRAVITATION
Earth attracts every object towards it by a force. This force is called force of gravitation or gravitational pull. This gravitational pull is also called as fore of attraction, as it attracts things towards earth. An object falls on the earth and this is due to force of Gravity or Gravitational pull. Example: When you…
