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 on the crate perpendicular to the surface.

Step2: Analyze gravity

The Earth's gravity acts downward on the crate.

Step3: Analyze applied force

The custodian applies a force to push the crate.

Step4: Analyze friction

Since the crate is moving on the floor, friction (kinetic) acts opposite to the direction of motion.

Step5: Analyze tension

There is no rope or string pulling the crate, so no tension.

Step6: Analyze air resistance

Assuming normal - speed pushing in a gym (not high - speed), air resistance is negligible.

Answer:

Normal, Gravity, Applied, Friction
