Force

 

A Force is that physical cause which changes or tends to change either the size or shape or the state of rest or motion of the body.

SI Unit of Force – Kg ms-2 or N (Newton).

There are 2 types, Contact and Non-Contact forces.

 

 

Contact Forces

 

The forces which act on bodies when they are in physical contact are called the Contact forces.

 

Examples of contact Forces:

 

Frictional Force:

When a body slide (or rolls) over a rough surface, a force starts acting on it in a direction opposite to its motion, along with the surface in contact. This force is called Frictional Force.

 

Normal Reaction Force:

When a body is placed on a surface, the body exerts a force equal to its weight downwards on the surface, but the body does not move or fall because the surface exerts an equal and opposite force on the body normal to the surface. This force is called the Normal Reaction Force.

 

Tension Force:

When a body is suspended by a string, the body, due to its weight W, pulls the string vertically downwards and the string in its stretched condition pulls the body upwards by a force that balances the weight of the body. This force is called the Tensile Force (T).

 

Spring Force:

If one end of a spring is kept fixed and its other end which is directly proportional to its displacement and is exerted in a direction opposite to the direction of displacement. This is called Spring/Restoring Force.

 

 

Non-Contact Forces

 

The forces experienced by bodies even without being physically touched are called the Non-Contact Forces or the Forces at a distance.

 

Examples of non-contact Forces:

 

Gravitational Forces:

The body on a force due to earth’s attraction is called the force of Gravity. In the universe, all particles attract one another due to its mass.

 

Electrostatic Force:

Two like charges repel and 2 unlike charges attract each other, the force between these charges is called Electrostatic Force.

 

Magnetic Force:

Two like magnetic poles repel and 2 unlike magnetic poles attract each other, the force between these magnetic poles is called Magnetic Force.
