1. What is Mechanical Energy Ratio?

The Mechanical Energy Ratio compares kinetic energy (KE) to potential energy (PE) in a system. It helps analyze energy transformations and conservation in mechanical systems.

2. How Does the Calculator Work?

The calculator uses the simple ratio formula:

Where:

• \( KE \) — Kinetic energy in joules
• \( PE \) — Potential energy in joules

Explanation: The ratio indicates how much kinetic energy exists relative to potential energy in the system.

3. Importance of Energy Ratio Calculation

Details: This ratio is crucial for understanding energy conservation in mechanical systems, analyzing pendulums, springs, and other oscillating systems.

4. Using the Calculator

Tips: Enter both KE and PE values in joules. PE cannot be zero (division by zero). Values must be non-negative.

5. Frequently Asked Questions (FAQ)

Q1: What does a ratio greater than 1 mean?
A: A ratio > 1 indicates the system has more kinetic energy than potential energy at the measured moment.

Q2: What's a typical ratio for a simple pendulum?
A: It varies between 0 (at extremes) and 1 (at bottom), showing energy transformation between KE and PE.

Q3: Can the ratio be negative?
A: No, since both KE and PE are always non-negative quantities.

Q4: How is this different from total mechanical energy?
A: Total mechanical energy is KE + PE, while this ratio shows their relative proportions.

Q5: When would this ratio be constant?
A: In a perfectly conservative system with no energy loss, the ratio would change predictably while KE + PE remains constant.
