Question

consider this situation: a student attaches a rope to his book bag and drags the bag across the floor at a constant speed. of the forces listed, identify which act upon the bag.
tap to select the forces that are present.
applied
gravity
normal
air resistance
tension
friction

Explanation:

• Gravity: Acts downward on the bag (pulls it towards the Earth).
• Normal Force: Acts upward (counteracts gravity as the bag is on the floor).
• Tension: In the rope (as the student pulls the bag).
• Friction: Opposes the motion of the bag (as it is dragged across the floor).
• Applied Force: The force exerted by the student through the rope.

Air resistance is negligible in this case (dragging a bag on the floor at a constant speed, air resistance is not a significant factor compared to the other forces).

Answer:

Gravity, Normal, Tension, Friction, Applied.
