You're interested in using mechanical energy to explore the motion of a ball you throw up in the air. Where do you need to put the origin of your y-axis? At the ground. Where the ball left your hand. At the ceiling. You're allowed to choose any origin you want.
Question
You're interested in using mechanical energy to explore the motion of a ball you throw up in the air. Where do you need to put the origin of your y-axis? At the ground. Where the ball left your hand. At the ceiling. You're allowed to choose any origin you want.
Solution
You're allowed to choose any origin you want. However, it's often most convenient to put the origin where the ball left your hand. This is because it simplifies the equations of motion. If you put the origin at the ground or at the ceiling, you would have to take into account the initial height of the ball, which can complicate the calculations. But ultimately, the choice of the origin does not affect the physics of the problem, only the form of the equations you use to describe it.
