Question
A child throws a ball up in the air.Which of the following statements is true?The store of GPE is staying the same.The store of GPE is increasing.The store of GPE is decreasing.
Solution
The statement "The store of GPE is increasing" is true.
Here's the step by step explanation:
-
GPE stands for Gravitational Potential Energy. This is the energy an object possesses because of its position relative to other objects, due to gravity.
-
When the child throws the ball up in the air, the ball gains height.
-
As the height of the ball increases, its gravitational potential energy also increases. This is because the ball is moving further from the Earth, and the force of gravity decreases with distance.
-
Therefore, as the ball is thrown up and gains height, the store of GPE is increasing.
-
Once the ball reaches its maximum height and starts to fall, the store of GPE will then start to decrease as the ball loses height and gets closer to the Earth. But the question is only asking about when the ball is thrown up, not when it falls back down.
So, the correct statement is "The store of GPE is increasing".
