Reducing friction – Odd one out

The video discusses various objects: an airplane, a racing car, a high-speed train, and a parachute. It identifies the parachute as the odd one out because, unlike the others, it is designed to increase friction rather than reduce it. The video explains how airplanes, racing cars, and high-speed trains are streamlined to minimize friction, enhancing their speed and efficiency. In contrast, parachutes are specifically designed to increase friction, which helps in slowing down descent.

Why is a parachute considered the odd one out among the listed objects?
