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 to support its weight.

Step2: Analyze gravity force

The Earth's gravitational pull acts down - ward on the crate.

Step3: Analyze applied force

The custodian is applying a force to push the crate across the floor.

Step4: Analyze friction force

As the crate moves across the floor, there is friction between the crate and the floor opposing the motion.

Step5: Analyze tension force

There are no ropes or strings pulling on the crate, so no tension force.

Step6: Analyze air - resistance force

The speed of the crate is likely low, and air - resistance is negligible in this situation.

Answer:

Normal, Gravity, Applied, Friction
