1. What is Kinetic Energy?

Kinetic energy is the energy possessed by an object due to its motion. It is measured in joules and depends on both the mass and velocity of the object.

2. How Does the Calculator Work?

The calculator uses the kinetic energy formula:

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: Kinetic energy calculations are essential in physics, engineering, and various 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 positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What units should I use for mass and velocity?
A: Mass should be in kilograms (kg) and velocity in meters per second (m/s) to get kinetic energy in joules.

Q2: Can I use this calculator for relativistic speeds?
A: No, this calculator uses the classical mechanics formula. For objects approaching the speed of light, relativistic equations should be used.

Q3: How does kinetic energy relate to work?
A: The work-energy theorem states that the net work done on an object equals its change in kinetic energy.

Q4: What is 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: Can kinetic energy be negative?
A: No, kinetic energy is always positive or zero (when velocity is zero) since both mass and velocity squared are always positive.
