Ratio of KE and GPE at various positions

Leave a comment

A ball in thrown vertically up. D is the highest point the ball reached. Find the ratio of KE at B to the PE at C.   ratio of ke and gpe

Solutions: 1 : 1

To solve such question, you have to apply conservation of energy. In other words, total energy of ball at any positions (A, B, C and D) is the same (no air resistance etc). There is no way to find KE as no speed is given. So to find KE, you need to find it indirectly with the help of PE.

Understand the concept here as there can be many variations of question asked.
