Want this question answered?
There are several forces involved while riding a skateboard. The force of friction (air resistance and contact with ground) acting against the motion and the pushing force from when you push off with your foot acting with motion. There are also several normal reaction forces, the weight of the person on the skateboard and the weight of the skateboard on the ground.
Friction
Gravity & Friction & support
the forces acting on the weight lifter and the weights are balanced because the forces are not moving or changing direction.
It is in Equilibrium and there are no forces acting on it.

If it is moving.
It will stop moving.

Maybe, maybe not. Forces don't happen because you're moving ... forces are what cause you to move. If there are no forces acting on you, then you keep moving whichever way you're moving, and your speed or direction don't change. If there are forces acting on you, then your speed and/or direction can change. If the force is in the same direction that you're already moving, you'll move faster (accelerate). If the force is in the direction opposite to the direction you're moving, then your speed will decrease. Does any of this sound surprising ???

If the object is not moving, then the only thing you can be sure of is that since it's not accelerating, all of the forces acting on it add up to zero. Just the fact that it's not moving is not enough information to tell you that there are no forces on it.
Yes...gravity
it will lost its balance and crash
