Question

If you were to sit on the ground, there would be a force due to gravity pulling you toward the earth. Which of the following is true according to Newton's 3rd law? A) The ground exerts an equal and opposite force on you. B) The ground exerts a force on you, but it is not equal and opposite. C) Gravity exerts a force on you, but you do not exert a force on the ground. D) There is no force acting on you when you sit on the ground.

Answer 1

According to Newton's 3rd law, the ground exerts an equal and opposite force on you when you sit on it.

Step-by-step explanation:

According to Newton's 3rd law, for every action, there is an equal and opposite reaction. When you sit on the ground, the force due to gravity pulling you towards the earth is the action. The reaction is the ground exerting an equal and opposite force on you, option A) The ground exerts an equal and opposite force on you. This is because the ground supports your weight by pushing against you with the same amount of force you exert on it. Therefore, option A) is true.
