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:

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

2. How Does the Calculator Work?

The calculator uses the kinetic energy equation:

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

Where:

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

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

3. Importance of Kinetic Energy Calculation

Details: Kinetic energy calculations are essential in physics, engineering, vehicle safety design, and understanding energy transfer in collisions.

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 standard unit is Joules (J) in the SI system, 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 is energy of motion, while potential is stored energy due to position or state.

Q4: Why is velocity squared in the formula?
A: Because both the force needed to accelerate an object and the distance over which it acts depend on velocity.

Q5: Can kinetic energy be negative?
A: No, since mass is always positive and velocity is squared, kinetic energy is always zero or positive.
