Question

question 9
apart from sky diving, propose two other examples of situations where balanced forces are acting on a moving object.

Explanation:

Balanced forces mean that the net force acting on an object is zero. When an object is moving with balanced forces, it will continue to move at a constant velocity. For a car moving at a constant speed on a straight road, the driving force from the engine is balanced by the frictional forces (air resistance and road - tire friction). In the case of a swimmer moving at a constant speed in a straight line in water, the force exerted by the swimmer's arms and legs (thrust) is balanced by the water resistance.

Answer:

1. A car moving at a constant speed on a straight road.
2. A swimmer moving at a constant speed in a straight line in water.
