Question

consider this situation: a custodian pushes a large crate across the gym floor. of the forces listed, identify which act upon the crate. tap to select the forces that are present. normal gravity applied friction tension air resistance

Explanation:

Step1: Analyze normal force

The floor exerts a normal force perpendicular to the surface of the crate to support its weight.

Step2: Analyze gravity

Gravity acts downward on the crate due to Earth's gravitational - pull.

Step3: Analyze applied force

The custodian applies a force to push the crate across the floor.

Step4: Analyze friction

There is friction between the crate and the gym - floor that opposes the motion of the crate.

Step5: Analyze tension

There is no rope or string attached to the crate, so no tension force.

Step6: Analyze air resistance

Since the crate is moving slowly across the floor, air resistance is negligible.

Answer:

Normal, Gravity, Applied, Friction
