The Conservation of Energy Calculator is a handy tool designed to evaluate the relationship between kinetic and potential energy within a physical system. It allows you to compute the missing variable when all other energy values are known, showcasing the principle that energy cannot be created or destroyed—only transformed.
Formula
The principle of conservation of energy is expressed as: initial kinetic energy plus initial potential energy equals final kinetic energy plus final potential energy.
How to use
To use the calculator, input the initial kinetic energy (Ki), the initial potential energy (Ui), and the final kinetic energy (Kf). Then click the “Calculate” button to find the final potential energy (Uf). The tool ensures the total energy before and after remains the same, assuming no loss to friction or other forces.
Example
If the initial kinetic energy is 30 J, the initial potential energy is 50 J, and the final kinetic energy is 60 J, then:
Total initial energy = 30 + 50 = 80 J
Final potential energy = 80 – 60 = 20 J
So, the final potential energy is 20 joules.
FAQs
- What is the Conservation of Energy Calculator?
It’s a tool that helps calculate one form of energy (usually final potential) when the others are known in a system. - What does conservation of energy mean?
It means the total energy of an isolated system remains constant over time. - What units are used in this calculator?
All energy values are in joules (J). - Can this be used for gravitational systems?
Yes, especially when working with potential and kinetic energy in gravitational contexts. - What if there is energy loss in the system?
This calculator assumes no energy loss due to friction, heat, or air resistance. - Can I calculate final kinetic energy instead?
Yes, just rearrange the equation and input the known values accordingly. - Is this calculator suitable for physics students?
Absolutely. It simplifies energy conservation problems for learning and verification. - What happens if I leave one field blank?
