INTRODUCTION

In our daily life we use different type of forces. The main types of forces are MUSCULAR FORCE, MAGNETIC FORCE, ELECTROSTATIC FORCE, GRAVITATIONAL FORCE, MECHANICAL FORCE, FRICTIONAL FORCE etc.

FORCEForce is that which changes or tends to change the shape ,size, volume , state of rest or state of motion.

TYPES OF FORCE

• CONTACT FORCE

• NON CONTACT FORCE

CONTACT FORCE

The force applied by the contact between objects is called contact force.E.g.-pushing a car , pulling a Trolley, throwing a ball.

NON CONTACT FORCE

The force applied on an object without contact on it is non contact force .Egg-a coconut falling from a coconut tree , a magnet attracting a nail.

FORCE

Contact force noncontact forceFrictional force

magnetic force gravitational force

electrostatic force

MAGNETIC FORCE

A magnetic has the property of attraction and repletion, this force applied by the magnet is the magnetic force.

ELECTROSTATIC FORCE.

A plastic pen when rubbed on hair can attract small pieces of pepper this is due to electrostatic forces.

GRAVITATIONAL FORCEObject in the universe have an attractive force between them, this attractive force is the gravitational forces.

MUSCULAR FORCE Man and other living creatures use muscular force to do work.

MECHANICAL FORCEForce in relation to motion is commonly known as mechanical force.

FRICTIONAL FORCEWhen an object moves over another object , the force which opposes the relative motion of the objects is the frictional forces.

CONCLUSION

Force and types of forces discussed here. They are muscular force, magnetic force ,electrostatic force , frictional force etc…………
