Air resistance and friction with the snow.
if there is friction on the hill it will slow you down
Friction.
inertia and friction are the two forces that slow down a rocket
FRICTION
Friction. And somewhat the gravity, which causes the friction.
Friction forces.

You need friction to slow down or turn while skiing and ice skating. Auto braking during driving. Walking or the movement of the motor vehicle depends on friction or there will not be movement.
Energy in motion can slow down due to factors like friction, air resistance, or other external forces acting on the object. These forces work against the motion of the object, converting its kinetic energy into other forms such as heat or sound, thereby causing the object to slow down.
The two forces that make a cyclist slow down are air resistance (drag) and friction. Air resistance occurs due to the drag force as the cyclist moves through the air, while friction between the bicycle tires and the road surface causes the bike to slow down.
Friction is the force that causes a marble to slow down and eventually stop when rolled along a floor. As the marble moves, it experiences opposing forces from the floor's surface, generating heat and slowing down the marble's motion.
Air Resistance mostly, and small amounts of gravity and friction with the road.
