Question

consider this situation: a child is holding onto a tree rope and swinging through the air. of the forces listed, identify which act upon the child. tap to select the forces that are present. normal gravity applied friction tension air resistance

Explanation:

Step1: Analyze gravity

Gravity pulls the child downwards towards the Earth's center. It is always present near the Earth's surface.

Step2: Analyze tension

The rope is under tension as it supports the child's weight and provides the centripetal - like force for the swinging motion.

Step3: Analyze air resistance

As the child is moving through the air, air resistance acts in the opposite direction of the child's motion, slowing down the swinging.

Step4: Analyze normal force

There is no surface in direct contact with the child (except the rope) to exert a normal force perpendicular to a surface, so normal force is not present.

Step5: Analyze applied force

There is no external agent actively applying a non - gravitational force to the child in this situation, so applied force is not present.

Step6: Analyze friction

There is no rubbing of the child against another solid surface in a way that would create friction relevant to the swinging motion, so friction is not present.

Answer:

Gravity, Tension, Air Resistance
