How and why is friction is cut down on a hovercraft?

Friction is reduced on a hovercraft by creating a cushion of air between the craft and the surface beneath it. This is achieved using large fans that blow air downward, generating lift and allowing the hovercraft to glide over various surfaces, including water and land. The reduction of contact with the ground minimizes friction, enabling smoother movement and greater efficiency. This design is particularly beneficial for navigating rough or uneven terrain.
