1. What Is Kinetic Energy?

Kinetic energy is the energy possessed by an object due to its motion. It is a scalar quantity that depends on both the mass and velocity of the object.

2. How Does The Calculator Work?

The calculator uses the kinetic energy formula:

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

Where:

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

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

3. Importance Of Kinetic Energy Calculation

Details: Calculating kinetic energy is essential in physics, engineering, and various real-world applications including vehicle safety design, sports science, and energy conservation studies.

4. Using The Calculator

Tips: Enter mass in kilograms and velocity in meters per second. Both values must be valid (mass > 0, velocity ≥ 0).

5. Frequently Asked Questions (FAQ)

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

Q2: Can kinetic energy be negative?
A: No, kinetic energy is always non-negative since mass is positive and velocity is squared.

Q3: How does mass affect kinetic energy?
A: Kinetic energy is directly proportional to mass - doubling the mass doubles the kinetic energy (at constant velocity).

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: Is this formula valid for all objects?
A: This formula applies to point masses and rigid bodies in translational motion. Different formulas are needed for rotational kinetic energy.
