Question

distinguish between contact and non contact force​

Answer 1

Answer:

Contact force occurs due to the contact between two different objects. Non-contact force occurs due to either attraction or repulsion between two objects such that there is no contact between these objects. ... The frictional force is an example of a contact force. Gravitational force is an example of a non-contact force.

Answer 2

Answer :-

Force is the vector quantity where both its magnitude and the direction are important. Force

is just the pull or the push acting upon the object. It takes place between the interactions between the two bodies. It can change the object's size, shape and speed of the object.

Complete step by step answer :-

Contact Forces ↓

1. Contact forces may or may not be the natural forces.
2. These forces require the physical touch or contact between the two on the object to work upon the object.
3. Since, in contact forces contact is to be made between the two object and therefore it does not work from the distance.
4. Contact force includes applied force, the normal force, the tension and the frictional force.

Non - Contact Forces ↓

1. Non-contact forces are the natural forces.
2. These forces do not require any physical touch to work on the object.
3. Since, in non-contact forces cannot is not required between the two objects and therefore it can work from a distance.
4. Non-contact force includes electro-magnetic force, the gravitational force and the electrostatic force.

Note: There are a number of types of the forces. Balanced forces - In balanced forces, two forces act opposite to each other with the same magnitude and as a result moving object will continue moving whereas the steady. For example - in tug of war if the magnitude of the force is the same on the both sides, the balanced force cancels each other and there will be no movement.
