What is force define the types …

A force is a push or pull acting upon an object as a result of its interaction with another object.

Types of forces:-

Contact Force :Forces which act on a body either directly or through a medium are called contact forces. The examples of contact forces are a Muscular force, mechanical force and Frictional Force. We can make use of muscular force of animals like bullocks, horses and camels to get the activities done. The frictional force is another type of contact force which acts between a pair of a surface in contact and tends to oppose the motion of one surface over the other.

Non-Contact Force :Forces which act through spaces without making direct contact with the body are called non-contact forces. The examples of non-contact forces are the Gravitational force, electrostatic force and magnetic force. The force exerted by a magnet on other magnets is called magnetic force. Magnetic force and electrostatic force act on an object from a distance, that’s the reason they are non-contact forces. The strength of gravity is an attractive force which is exerted by the Earth on objects which make them fall to the land. The weight of a body is the force which is pulled by the earth towards the centre.

The magnitude of the force is given by the product of the mass of the object (m) and its acceleration (a). 

F = ma

Contact Forces are Frictional Force , Tension Force,  Normal Force, Air Resistance Force, Applied Force, Spring Force.

Non-Contact Forces are Gravitational Force,  Electrical Force,  Magnetic Force.
