Question

consider this situation: a person stands at rest on the floor. identify the forces that act upon the person. tap to select the forces that are present. normal gravity applied friction tension air resistance check answers

Explanation:

Step1: Analyze gravitational force

The Earth's gravity pulls the person downwards towards the center of the Earth. This is always present near the Earth's surface for any object with mass.

Step2: Analyze normal force

The floor exerts an upward - acting normal force on the person. Since the person is at rest, according to Newton's first law, the net force on the person is zero. The normal force balances the gravitational force.

Step3: Analyze other forces

There is no applied force (no external push or pull), no friction (no relative motion or tendency of relative motion between the person and the floor), no tension (no ropes or strings pulling on the person), and air - resistance is negligible as the person is at rest.

Answer:

Normal, Gravity
