Question

consider this situation: a moving shuffle board disk skids to a stop across an asphalt surface. of the forces listed, identify which act upon the disk. tap to select the forces that are present. normal gravity applied friction tension air resistance

Explanation:

Step1: Analyze normal force

The disk is on a surface, so the surface exerts a normal force perpendicular to the surface, supporting the disk against gravity.

Step2: Analyze gravity

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

Step3: Analyze applied force

There is no external force being actively applied to the disk as it skids to a stop.

Step4: Analyze friction

The disk skids across the asphalt, and friction between the disk and the asphalt surface acts to slow it down.

Step5: Analyze tension

There are no ropes or strings attached to the disk, so no tension force is present.

Step6: Analyze air resistance

Although usually small, air resistance acts on the moving disk opposite to its direction of motion.

Answer:

Normal, Gravity, Friction, Air Resistance
