Question

Distinguish between balance and unbalance force contact and noncontact force

Answer 1

Balanced force

• A force where two forces of equal size, act on a body,in opposing directions is known as balanced force.
• The sum of all forces or net force acting on an object is zero.
• It doesn't affect the state of motion of the object.

Unbalance force

• A force where two forces acting in opposing directions on a body, and are not equal in magnitude or size is known as unbalanced force.
• The sum of all forces acting on an object is non zero.
• It chanfes the state of motion of the object.

Contact force

• Force arises due to the contact between two different objects.
• It is the force exerted by a body when there is a direct contact between them.
• It is a push or pull on one object by the other that is touching it.

Non contact force

• Force arises due to attraction or repulsion between two objects, there is no contact between the objects.
• It is a force that acts on an object without coming physically in contact with it.
• It is a force that one object can apply to another object without touching it.
