1. What Are Potential And Kinetic Energy?

Potential Energy (PE) is the energy stored in an object due to its position relative to a reference point, while Kinetic Energy (KE) is the energy possessed by an object due to its motion. Both are fundamental concepts in physics.

2. How Does The Calculator Work?

The calculator uses the standard physics equations:

Where:

• \( m \) — Mass of the object (kg)
• \( g \) — Acceleration due to gravity (m/s²)
• \( h \) — Height above reference point (m)
• \( v \) — Velocity of the object (m/s)

Explanation: Potential energy depends on mass, gravity, and height, while kinetic energy depends on mass and the square of velocity.

3. Importance Of Energy Calculations

Details: Understanding energy calculations is essential in physics, engineering, and various real-world applications including mechanical systems, energy conservation, and motion analysis.

4. Using The Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What is the standard value for gravity on Earth?
A: The standard acceleration due to gravity on Earth is approximately 9.81 m/s².

Q2: Can potential energy be negative?
A: Yes, potential energy can be negative depending on the reference point chosen for height measurement.

Q3: How are these energy values related?
A: In many physical systems, potential energy can be converted to kinetic energy and vice versa, following the principle of conservation of energy.

Q4: What units are used for energy calculations?
A: The standard SI unit for energy is the joule (J), where 1 J = 1 kg·m²/s².

Q5: Are there different types of potential energy?
A: Yes, besides gravitational potential energy, there are other forms such as elastic potential energy, chemical potential energy, and electrical potential energy.
