Question

consider this situation: a feather is falling towards the ground at a constant speed. of the forces listed, identify which act upon the feather. tap to select the forces that are present. normal gravity applied friction tension air resistance

Explanation:

Step1: Analyze gravity

Gravity always acts on objects near the Earth's surface, pulling them downwards. So gravity acts on the feather.

Step2: Analyze air - resistance

Since the feather is falling at a constant speed, there must be a force opposing the motion of the feather. In the air, this force is air - resistance.

Step3: Analyze other forces

There is no surface in contact with the feather to exert a normal force. There is no external push or pull to be an applied force. There is no string or cable attached to the feather for tension to act. And friction usually acts between solid surfaces in contact, so it does not apply here.

Answer:

Gravity, Air Resistance
