The angle at which a projectile leaves the ground and gains maximum horizontal displacement. When the height of release and landing are the same, assuming no air resistance, the theoretical optimal angle of release is 45° However, the actual optimal angle is usually 35–45° to compensate for the effects of air resistance. When the height of release is greater than the height of landing, as in shot-putting, the optimum angle is always less than 45°. When the height of release is less than the height of landing, for example when playing a bunker shot in golf, the optimal angle is more than 45°.
