What is the curved path that an object follows when thrown or launched near Earth's surface?

• A. Displacement
• B. Field Force
• C. Projectile Motion
• D. Gravity

Answer: (C)

Projectile motion describes the curved trajectory of a thrown or launched object near Earth, assuming air resistance is negligible. Gravity provides a constant downward acceleration, so the vertical position changes with time as y ≈ y0 + v_y0 t − (1/2) g t^2, while the horizontal motion is nearly at constant speed, x ≈ x0 + v_x0 t. The combination of these two independent motions makes the path a parabola when plotted in horizontal versus vertical coordinates. Gravity is the force that causes the curvature, not the path itself; displacement refers to the straight-line difference between start and end, and field force is not the description of the trajectory.
