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 force due to Earth's pull

Gravity is always present near the Earth's surface and acts down - ward on the feather, pulling it towards the ground.

Step2: Consider air resistance

Since the feather is falling through air, air resistance acts in the opposite direction of its motion. As it is falling at a constant speed, the air resistance balances the force of gravity.

Step3: Evaluate other forces

There is no normal force as the feather is not in contact with a solid surface in a way that would cause a normal force. There is no applied force as no external agent is actively pushing or pulling it other than gravity. There is no tension as there is no string or cable attached to it. Friction is not relevant in the context of this free - falling situation through air.

Answer:

Gravity, Air Resistance
