1. What Are Kinetic and Potential Energy?

Kinetic energy (KE) is the energy possessed by an object due to its motion, while potential energy (PE) is the energy stored in an object due to its position or configuration. These are fundamental concepts in physics that describe different forms of mechanical energy.

2. How Does the Calculator Work?

The calculator uses the standard physics equations:

\[ KE = \frac{1}{2} m v^2 \] \[ PE = m g h \]

Where:

\( KE \) — Kinetic Energy (Joules)
\( PE \) — Potential Energy (Joules)
\( m \) — Mass (kilograms)
\( v \) — Velocity (meters per second)
\( g \) — Gravitational acceleration (m/s², typically 9.81)
\( h \) — Height (meters)

Explanation: Kinetic energy increases with the square of velocity, while potential energy increases linearly with height and gravitational acceleration.

3. Importance of Energy Calculations

Details: Energy calculations are essential in physics, engineering, and various practical applications including mechanical systems, energy conservation analysis, and understanding motion dynamics.

4. Using the Calculator

Tips: Enter mass in kilograms, velocity in m/s, height in meters, and gravitational acceleration (default is Earth's gravity 9.81 m/s²). All values must be positive.

5. Frequently Asked Questions (FAQ)

Q1: What units should I use for the inputs?
A: Use kilograms for mass, meters per second for velocity, meters for height, and m/s² for gravity to get results in Joules.

Q2: Can I calculate energy for objects on other planets?
A: Yes, simply adjust the gravity value to match the gravitational acceleration of the other celestial body.

Q3: What if velocity is zero?
A: If velocity is zero, kinetic energy will be zero regardless of mass, as the object is not moving.

Q4: What if height is zero?
A: If height is zero (reference point), potential energy will be zero regardless of mass and gravity.

Q5: Are there other forms of potential energy?
A: Yes, this calculator only calculates gravitational potential energy. Other forms include elastic, chemical, and electrical potential energy.
