A person throwing a rock.

Reason: once released the rock moves through the air under gravity (neglecting air resistance) and follows a curved (parabolic) path. The swing is constrained by the rope (pendulum motion), the runner stays in contact with the ground, and picking up a pencil is not free flight.
