Quizplus · Accepted Answer

When a coin is tossed upwardly, the only force acting on it is gravity pulling it towards the earth. At the highest point of its trajectory, the coin comes to a momentary rest before it begins to fall back down due to the same force of gravity. Thus, during this instant, there is only one force acting on the coin, and that is the force of gravity.
