1. What is the Kinetic Energy Formula?

The kinetic energy formula calculates the energy possessed by an object due to its motion. It is given by KE = (1/2) × m × v², where m is mass and v is velocity.

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 (kilograms)
\( v \) — Velocity (meters per second)

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: Kinetic energy calculations are fundamental in physics for understanding motion, collisions, energy transfer, and various engineering applications.

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: Kinetic energy is measured in Joules (J) in the SI system.

Q2: How does velocity affect kinetic energy?
A: Kinetic energy increases with the square of velocity, meaning doubling velocity quadruples kinetic energy.

Q3: Can kinetic energy be negative?
A: No, kinetic energy is always a positive quantity or zero for stationary objects.

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 used for rotational kinetic energy.
