Answer 1

Answer:

When two forces acting on an object are equal in size but act in opposite directions, we say that they are balanced forces

Answer 2

If the forward force on an object is equal to the forces of friction and air resistance, we say that the forces are balanced.

Explanation:

Balanced Force

• In the case of balanced force, the body is acted upon by forces in opposite direction.
• When equal forces act in each direction, it results in zero net force. And the body remains in equilibrium state.
• There is no acceleration in the body.
• Example: When a body is pushed from one side with a force of 5 Newton and also pushed from opposite side with a force of 5 Newton, then the body will remain in equilibrium state as both the forces will cancel out each other.
• Friction is a contact force that opposes the direction of motion of any object.
• Air resistance also opposes the direction of motion of object.
• So, if sum of both friction and air resistance is equal to the forward force then the force is balanced.
