Why does Jessica fall towards the Earth when she stumbles while roller boarding?
Jessica's weight is 540 newtons. According to Newton's Third Law, if the Earth pulls on Jessica with a force of 540 N, then Jessica pulls on the Earth with a force of 540 newtons that acts in the opposite direction. However, if Jessica stumbles while roller blading, she will fall down to the ground. Explain why this happens.

Jessica's weight is 540 N. By Newton's third law that states for every action there is an equal and opposite reaction, the Earth is exerting an attractive force of 540 N on Jessica and Jessica is exerting an attractive force of 540 N on the Earth.
I assume your question is why Jessica should fall towards the Earth when she stumbles while rollerblading instead of staying still. Her fall is due to the attractive force of the Earth that pulls her with a force of 540 N. It should also be noted that Jessica also pulls the Earth towards herself but the acceleration caused to the Earth due to a force of 540 N is almost zero as the mass of the Earth is very large.
