1. What is Kinetic Energy?

Kinetic energy is the energy possessed by an object due to its motion. The total kinetic energy of a system is the sum of the kinetic energies of all its components.

2. How Does the Calculator Work?

The calculator uses the kinetic energy equation:

\[ KE_{total} = \sum 0.5 \times m \times v^2 \]

Where:

\( m \) — Mass of the object (kg)
\( v \) — Velocity of the object (m/s)
\( KE_{total} \) — Total kinetic energy (Joules)

Explanation: The equation shows that kinetic energy is proportional to the mass of the object and the square of its velocity.

3. Importance of Kinetic Energy Calculation

Details: Calculating kinetic energy is essential in physics and engineering for understanding motion, collisions, energy conservation, and designing 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 velocity affect kinetic energy?
A: Kinetic energy increases with the square of velocity - doubling speed quadruples the kinetic energy.

Q3: Can kinetic energy be negative?
A: No, kinetic energy is always positive or zero (when velocity is zero).

Q4: 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.

Q5: How is this different from relativistic kinetic energy?
A: This is classical kinetic energy. For objects approaching light speed, the relativistic formula must be used.
