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 gravity force

Gravity acts on all objects near the Earth's surface, pulling the crate downwards.

Step2: Analyze normal force

The ramp exerts a normal force perpendicular to its surface on the crate to support it.

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 any external applied force on the crate in the given situation.

Step5: Analyze tension force

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

Step6: Analyze air - resistance force

The situation does not imply any motion through air at a significant speed, so no air - resistance.

Answer:

Normal, Gravity, Friction
