Jessica's weight is 540 Newtons. According to the Third Law, if the Earth pulls on Jessica with a force of 540N, then Jessica pulls on the Earth with a force of 540 Newtons that acts in the opposite direction. However, if Jessica stumbles while rollerblading, she wil lfall down to the ground. Explain why this happens

  When she stumbles, the forces are still there, they dont go away. She accelerates to the ground (F=ma) as the Earth accelerates toward her (F=Me*a) Such is life.
