Thank you Professor for explaining such detail aspects of Conservation of energy. This is helping me to do well in Physics. It has become my favorite subject recently. Thank you for your dedication.

Isn't Velocity a vector, So shouldn't it have direction then?

Dear Professor, What happens if there was spring at certain height, and then compressed and the object goes up and falls to the ground. So now I need to factor in the Spring Potential Energy. How would this work when finding Final velocity,
Should this be the equation, 1/2kA^2i + mghi + 1/2mv^2i = 1/2mv^2f
