Which outcome occurs when a trebuchet's counterweight is released from an elevated position?

💡 Explanation

When the counterweight is released, gravitational potential energy is converted into kinetic energy via the rotation of the beam arm, launching the projectile. Therefore kinetic energy increases, rather than just projectile velocity, rotational inertia, or base structural stress which are secondary or localized effects.
