1. What is Conservation Of Mechanical Energy?

The principle of conservation of mechanical energy states that in an isolated system with only conservative forces acting, the total mechanical energy (sum of kinetic and potential energy) remains constant. This is a fundamental concept in classical mechanics.

2. How Does the Calculator Work?

The calculator uses the conservation of mechanical energy equation:

\[ KE_i + PE_i = KE_f + PE_f \]

Where:

\( KE_i \) — Initial kinetic energy (J)
\( PE_i \) — Initial potential energy (J)
\( KE_f \) — Final kinetic energy (J)
\( PE_f \) — Final potential energy (J)

Explanation: The calculator verifies whether the total mechanical energy remains constant between two states, indicating whether energy is conserved in the system.

3. Importance of Mechanical Energy Conservation

Details: This principle is crucial for analyzing mechanical systems, predicting motion, and solving problems in physics without needing to know the detailed forces acting throughout the process.

4. Using the Calculator

Tips: Enter all energy values in joules (J). The calculator will determine if mechanical energy is conserved between the initial and final states.

5. Frequently Asked Questions (FAQ)

Q1: When does mechanical energy conservation apply?
A: Only in systems where only conservative forces (like gravity, spring force) act and no energy is dissipated through friction or other non-conservative forces.

Q2: What if energy is not conserved?
A: If energy is not conserved, it means non-conservative forces (like friction) are doing work on the system, converting mechanical energy to other forms like heat.

Q3: Can potential energy be negative?
A: Yes, depending on the reference point chosen. However, this calculator assumes all values are positive for simplicity.

Q4: What types of potential energy are included?
A: This calculator works for any form of potential energy (gravitational, elastic, etc.) as long as all values are provided in joules.

Q5: How precise is the calculation?
A: The calculator uses a tolerance of 0.0001 J to account for potential rounding errors in input values.
