questions
Hi Jbignes5,
Gravity isn't a constant any more than light is a constant. Gravity and light are averaged. Light is slower by mass and faster away from mass.
Anyway, I have a couple questions for you for now.
Question 1: If it requires 1 joule to raise a small apple 20cm, accounting for losses, about how many joules would you actually have to expend in order to get that apple up? 1.1, 1.2, 1.3? Just a simple guess is good for the example.
Question 2: To raise that apple, do you consider that to be work performed?
Question 3: Once the apple is raised to 20cm and is sitting there, would you say that it has 1 joule of potential energy (close enough estimate)?
Question 4: Is work being performed when a leaf blows in the wind?
