Distinguish between:
(a) balanced and unbalanced forces.
(b) contact and non-contact forces.
Answers
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. ... Balanced forces cause a still object to remain at rest. As against this, the unbalanced forces cause a stationary object to move in the direction of the greater force.
(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.

(b) The contact force acts on a point of direct contact between the two objects.

Difference between contact and non-contact force.
Contact forces Non-contact force
The frictional force is an example of a contact force. Gravitational force is an example of a non-contact force.
