Answer: Yes, in the interaction between Earth and the moon, Earth and the moon pull simultaneously on each other. Earth pulls on the moon while the moon pulls on Earth. Both pulls make up an action-reaction pair, are opposite in direction to each other, and have equal strength.

Answer: To identify a pair of action-reaction forces in any situation, first identify the pair of interacting objects involved. In this case, the interaction is the gravitational attraction between the falling object and another object, possibly a distant planet. So the planet pulls down on the object (action), while the object pulls up on the planet (reaction).

Answer: The ball will accelerate, which does not contradict Newton's third law. Instead, the kick acts on the ball so no other force has been applied to it. The net force on the ball is very real and therefore it accelerates. The reaction force however acts on your foot, not on the ball. This force causes your foot to decelerate as it makes contact with the ball.
