1. What is Kinetic Energy?

Kinetic energy is the energy possessed by an object due to its motion. It depends on the mass of the object and the square of its velocity, as described by the equation KE = ½mv².

2. How Does the Calculator Work?

The calculator uses the kinetic energy equation:

Where:

• \( KE \) — Kinetic energy (Joules)
• \( m \) — Mass of the object (kilograms)
• \( v \) — Velocity of the object (meters per second)

Explanation: The energy increases with the square of velocity, meaning doubling speed quadruples the kinetic energy.

3. Importance of Kinetic Energy Calculation

Details: Kinetic energy calculations are fundamental in physics, engineering, and safety analysis, particularly in transportation, sports, and mechanical systems.

4. Using the Calculator

Tips: Enter mass in kilograms and velocity in meters per second. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What are the units of kinetic energy?
A: The SI unit is Joules (J), where 1 J = 1 kg·m²/s².

Q2: How does kinetic energy relate to work?
A: The work done on an object equals its change in kinetic energy (Work-Energy Theorem).

Q3: What's the difference between kinetic and potential energy?
A: Kinetic energy is energy of motion, while potential energy is stored energy due to position or configuration.

Q4: Can kinetic energy be negative?
A: No, kinetic energy is always positive or zero (when velocity is zero).

Q5: How is kinetic energy used in real-world applications?
A: It's used in crash testing, ballistics, renewable energy systems, and understanding particle physics.
