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 formula 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 equation shows that kinetic energy increases with the square of velocity, meaning doubling speed quadruples kinetic energy.

3. Importance of Kinetic Energy Calculation

Details: Calculating kinetic energy is essential in physics, engineering, and safety analysis to understand the energy involved in moving objects, from vehicles to particles.

4. Using the Calculator

Tips: Enter mass in kilograms and velocity in meters per second. Both 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, since both mass is always positive and velocity is squared, kinetic energy is always zero or positive.

Q5: How is kinetic energy used in real-world applications?
A: It's used in vehicle safety design, sports science, particle physics, and energy generation (e.g., wind turbines).
