yes almost every moving and moving object has to do with friction. Friction is force resisting the relative motion of two surfaces in contact or a surface, Such as skate board wheels and the ground.
The main forces acting on a moving skateboard are friction with the ground, air resistance, and the force applied by the skater to propel the skateboard forward. Additionally, there may be gravitational forces affecting the vertical motion of the skateboard.
The main forces acting on a skateboard are gravitational force pulling it downward, normal force exerted by the ground upward, frictional force opposing its motion, and air resistance when moving. Additionally, the skater applies a force to propel the skateboard forward and can use their body to maneuver and balance it.

American ground forces were directly involved in the war between 1965 and 1973.
gravity
This is a mighty vague question, but I'll give it a shoot. A skateboard has wheels - when these wheels are acted upon by a force (such as you pushing it), they proceed to take the energy from that force and change it into centrifugal and centripetal forces- this causes the wheels on your skateboard to turn. Your skateboard won't roll indefinitely from 1 push because while your skateboard is rolling it is creating friction with the sidewalk you're skateboarding on. Friction is caused when 2 objects rub up against each other - this creates heat and a transfer of kinetic energy. Once all the kinetic energy has been transferred from your skateboard's wheels to the sidewalk, your skateboard come to a stop.
The Allied forces got involved in the Russian Civil War in order to back the anti-Bolshevik White forces. The Allies were worried after the collapse of the Eastern front.
name tge two forces involved in the attle of pasir panjang in world war 2 ?
No, objects do not have to touch for a force to be involved. Forces, such as gravitational or electromagnetic forces, can act between objects even when they are not in direct contact.
I wasn't aware of any Allied forces involved in Russia's civil war. I think you must be mistaken.
