The conversation between human and AI assistant.
You push backward against the ground to move a skateboard forward. The force you make acts against the ground. What force acts against you to move you forward?
I have a physics question. When you push backward against the ground to move a skateboard forward, what force acts against you to move you forward?
The force that acts against you to move you forward is actually the force of friction. As your skateboard wheels move forward, the ground offers resistance which pushes you in the opposite direction.
