Question

When a person jumps up,

(A) he exerts a force on the ground
(B) the ground exerts a force on him
(C) Both (A) and (B) are true
(D) Both (A) and (B) are false

Answer 1

C) As person exerts force on the ground opposite to the direction of the force applied by the ground , so option c is correct.

Answer 2

(C) Both (A) and (B) are true

As you walk around, you are continuously using action-reaction force pairings. We thrust down on the floor when we jump. The ground then pulls you up against it. You are propelled into the air by this upward force. Because they act on different systems, two equal and opposite forces do not neutralize. A surfer pushing off a barrier, aircraft creating lift by pushing airflow, and an octopus moving itself ahead by expelling water from its body are examples of action-reaction pairings.
