Question

question 1 (1 point)
you are standing in a moving skateboard, facing forward, and you suddenly fall forward as the skateboard hits a curb. what force caused you to fall forward?
○ force due to friction between you and the floor of the bus
○ gravity
○ normal force due to your contact with the floor of the bus
○ there is not a force leading to your fall.

Explanation:

When the skateboard hits the curb, it stops, but your body (due to inertia, a property of matter to stay in its state of motion) continues moving forward. There's no force causing the fall directly; the fall is due to inertia (lack of a force to stop your forward motion instantly like the skateboard). The other options: friction (not relevant here as the fall is about inertia), gravity (acts downward, not causing forward fall), normal force (vertical, not forward - related). So the correct reasoning is that the fall is due to inertia, meaning no force causes it in the way the other options suggest.

Answer:

D. There is not a force leading to your fall.
