A pull or push acting on a body which tends to change the state of motion or rest of an object is termed as Force..
A force can change the state of rest..
Eg when we kick a football which is at rest will come in motion..
If we will stop a cricket ball in motion , then it will come in rest..

A force can be defined as a push or a pull which acts upon an object as a result of its interaction with another object.
Examples of forces
Weight
Weight is the force of gravity, which is the pull of the Earth on an object. To understand the force of gravity the concept of mass needs to be understood as well.
The mass of an object is the amount of matter it contains. Thus mass is a measure of how much stuff is in an object. Mass is measured in kilograms (kg) and is the same no matter where the object is located in the universe. For example and object of mass 10kg on the Earth will have the same mass of 10kg on the moon or anywhere else in the universe. Weight on the other hand is a measure of the pull of a planet i.e. Earth on the stuff contained in the object. The direction of the force of gravity is downwards towards the centre of the Earth.
Friction
Frictional forces are the forces that oppose or prevent motion. These forces are a result of the interaction between the surfaces of two objects (more precisely due to the attractions between the molecules of the surfaces in contact). The reason why a football that is kicked eventually comes to rest is due to the friction forces between the surface of the rolling ball and the grass and air it is in contact with.
Magnetic Forces
This is the force produced by magnetic materials which pulls or repels other materials. For example the magnetic strip on a refrigerator door catch pulls the door to the refrigerator frame to keep the door closed.
