The first statement is correct: the force of gravity works against the skateboarders’ inertia.
Brief explanation: when they leave the ramp they become a projectile. Their inertia keeps them moving forward, but gravity applies a downward force that accelerates them toward Earth, so they follow a curved (parabolic) path and come back down. Wheel spin or “using Newtons” are not reasons—wheels don’t keep you airborne, and “Newtons” are just units of force.
