Question

consider this situation: a large crate is at rest on a ramp at a loading dock. 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 ramp exerts a normal force perpendicular to its surface on the crate.

Step2: Analyze gravitational force

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

Step3: Analyze friction force

Since the crate is at rest on the ramp, static - friction acts to prevent it from sliding down.

Step4: Analyze applied force

There is no mention of an external applied force on the crate.

Step5: Analyze tension force

There are no ropes or strings attached to the crate, so no tension.

Step6: Analyze air - resistance force

The crate is at rest, and air - resistance is negligible in this static situation.

Answer:

Normal, Gravity, Friction
