Gravity, friction, or wind drag.
friction
When you increase your velocity on a skateboard it is harder to stop because of momentum.

Skiers reduce friction by waxing the base of their skis, which helps them glide more smoothly over the snow. Additionally, skiers can also adjust their body position and movements to minimize resistance and increase speed. Also, using properly maintained equipment and choosing the right wax for the snow conditions can help reduce friction.
the friction between the wheels and the surface of the ground affect the speed of the skateboard. fo instance if you ride the skateboard on a smooth surface (with less friction) the skateboard will go faster.
Using sandpaper to increase friction on a slippery surface, such as on the bottom of shoes for better grip.
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.
For a skateboard, friction works between the wheels of the board and the axis, as well as between the wheels of the board and the ground when the board is in motion. Since friction works in a direction opposing motion, it is only in effect when the when the board or the wheels of the board are in motion.
This is an example of inertia, specifically Newton's first law of motion. An object in motion tends to stay in motion unless acted upon by an external force, in this case friction between the skateboard wheels and the ground.
