Gravitational Potential Energy
Example of conservation of energy
- Assume the energy is all gravitational or kinetic energy.
- That is we assume there is no input from an engine, no loss to heat or other conversion of energy to other forms
Use conservation of E = mgh + ½ m v2
If v= 0 at h = htop, what is v at h = htop - 1 m?
What is v at h = htop - 2 m?
