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:

Where:

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

Explanation: The formula shows that kinetic energy is proportional to the mass of the object and proportional to the square of its velocity.

3. Importance of Kinetic Energy Calculation

Details: Calculating kinetic energy is essential in physics and engineering for understanding motion, collisions, energy conservation, and designing safety systems.

4. Using the Calculator

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

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 the velocity quadruples the kinetic energy.

Q3: Can kinetic energy be negative?
A: No, kinetic energy is always a positive quantity since both mass and velocity squared are always positive.

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 is valid for point masses and rigid bodies moving at non-relativistic speeds (much less than the speed of light).
