The friction between the foot and the ground creates a force that opposes the motion of the skateboard, causing it to slow down. This friction converts the kinetic energy of the skateboard into thermal energy.

it change into potential energy beace it slows down
As the skateboard slows down and comes to a stop, the kinetic energy is transferred into other forms, mainly heat and sound. Friction between the wheels and the surface, as well as air resistance, cause the skateboard's kinetic energy to be dissipated as heat and sound energy.
The limiting frictional force is the force that slows down the tennis ball on the roller coaster.
Air resistance.

reduces
Gravity is the force that causes objects to fall, while air resistance or drag slows down a falling object as it moves through the air. The larger the surface area of the object, the greater the air resistance force, which opposes the force of gravity and slows the object down.
