Question

Distinguish between:
(a) balanced and unbalanced forces.
(b) contact and non-contact forces.​

Answer 1

Answer:

a.)

In balanced forces, the magnitude of the two forces is equal, whereas, in the case of unbalanced forces, the magnitude of the two forces are unequal. In balanced forces, the two individual forces act in opposite direction. Conversely, in unbalanced forces, the individual forces either act in same or opposite direction

B .) 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. There is no field linked with the contact force. There is always a field linked with non-contact force.

Answer 2

In balanced forces, the two individual forces act in opposite direction. Conversely, in unbalanced forces, the individual forces either act in same or opposite direction. A non-contact force is a force which acts on an object without coming physically in contact with it.

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
