1. What is Kinetic Energy?

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

2. How Does the Calculator Work?

The calculator uses the kinetic energy equation:

\[ KE = \frac{1}{2} \times m \times v^2 \]

Where:

\( m \) — Mass of the object (kg)
\( v \) — Velocity of the object (m/s)
\( KE \) — Kinetic energy (Joules)

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

3. Importance of Kinetic Energy Calculation

Details: Kinetic energy calculations are fundamental in physics, engineering, and safety analysis. They're used in vehicle safety design, sports science, and understanding particle physics.

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 non-negative since mass is positive and velocity is squared.

Q5: How is kinetic energy used in real-world applications?
A: It's used in calculating braking distances, designing safety features, analyzing collisions, and understanding planetary motion.
