Complete 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.
a. Normal Force
b. Gravity Force
c. Applied Force
d. Friction Force
e. Tension Force
f. Air Resistance Force
Answer:
Following are the forces that act upon the disk:
a. Normal Force
b. Gravity Force
d. Friction Force
f. Air Resistance Force
Step-by-step explanation:
Normal force is acting upon the disk as the block is supported by the Asphalt surface. It is equal to the Gravitational Force acting upon the disk.
Gravity Force is acting upon the disk as Earth attracts every object on its surface.
Applied Force is absent. Applied Force acted to bring the disk into motion but at the moment when shuffle board disk is moving across an asphalt surface, no applied forces are acting upon it. It is the inertia that keeps it moving.
Friction Force is acting upon the disk as the asphalt surface is slowing down the skidding disk.
There is no tension in the disk as there is no unrelaxed string attached to the disk.
The disk is moving relative to the surrounding air, it means that air resistance is there.
