Question

you try to push a box across the floor, but it doesnt move. what force is stopping it from sliding?
○ gravity
○ air resistance
○ friction
○ tension

Explanation:

• Gravity acts vertically downward, not opposing horizontal sliding.
• Air resistance is negligible for a box on a floor.
• Tension is a force in ropes/cables, not relevant here.
• Friction opposes the relative motion between the box and the floor, preventing it from sliding when pushed.

Answer:

C. Friction
