1. What Is Kinetic Energy?

Kinetic energy is the energy possessed by an object due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity.

2. How The Calculator Works

The calculator uses the kinetic energy formula:

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

Where:

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 essential in physics, engineering, automotive safety, sports science, and many other fields to understand energy transfer and impact forces.

4. Using The Calculator

Tips: Enter mass in kilograms and velocity in meters per second. All values must be positive numbers. The calculator provides both the final result and a detailed step-by-step solution.

5. Frequently Asked Questions (FAQ)

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

Q2: How does mass affect kinetic energy?
A: Kinetic energy is directly proportional to mass - doubling the mass doubles the kinetic energy (if velocity remains constant).

Q3: Why is velocity squared in the formula?
A: Velocity is squared because the work needed to accelerate an object increases with the square of the final velocity.

Q4: Can kinetic energy be negative?
A: No, kinetic energy is always positive or zero (when velocity is zero) since both mass and the square of velocity are always non-negative.

Q5: 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.
