Law #1 Law of Motion
The foot is the unbalanced force because it is being accelerated and is acting upon the balanced force which is is the soccer ball not moving until it is kicked by the foot.
The two skateboards have different net force, the one on top is being pushed slower and also has to deal with friction and the skateboard on the bottom is being pushed faster and also has to deal with friction.
The net force for the bottom skateboard is greater than the top.
The net force is all forces that are acting upon an object added up.
A very relatable example is bouncing on a trampoline.
You jump on the trampoline and when you land and bounce up that's the trampoline applying an equal and opposite reaction.
And my science journal.
And my background knowledge.
And most importantly, MattyBRaps!
