Question

how does newtons first law apply when you run into a wall on a motorcyle using the word action force

Answer 1

Newton's First Law of Motion states that an object at rest will remain at rest, and an object in motion will continue in motion at a constant velocity unless acted upon by a net external force. When you run into a wall on a motorcycle, this principle is clearly illustrated.

As you ride the motorcycle, both you and the motorcycle are in motion. When you hit the wall, the wall exerts an action force on the motorcycle and you, acting as the external force that brings your motion to a stop. This force is typically very strong and sudden, effectively changing your state of motion.

According to Newton's Third Law, for every action, there is an equal and opposite reaction. In this scenario, the action force is the wall pushing against the motorcycle and you as you collide with it. In response to that action force, your body will experience a reactive force which can result in a sudden deceleration. The momentum of both you and the motorcycle is abruptly halted, which may lead to injury due to the rapid change in motion and the internal forces acting on your body.

So, in summary, when you collide with the wall, the action force exerted by the wall is what changes your state of motion, in alignment with Newton's First Law. Your body, along with the motorcycle, experiences a dramatic change in velocity due to the external force applied by the wall.
