JUNIOR Class 5 General Science Force and Energy
Force
Force is defined as push or pull.
Friction force resists motion between two objects that are in contact with each other.
If the resultant of all the forces acting on a body is zero, the forces are called balanced forces and if the resultant of all the forces acting on a body is non zero, the forces are called unbalanced forces.Energy
An object having a capability to do work is said to possess energy.
The energy possessed by a body by virtue of its motion is called kinetic energy.
The energy possessed by a body by virtue of its position or change in configuration is called potential energy.
Power is the rate at which work is done.
