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. The greater the mass and velocity, the greater the kinetic energy.

2. How Does the Calculator Work?

The calculator uses the kinetic energy equation:

Where:

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

Explanation: The equation 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 energy conservation, collision dynamics, and designing safety systems. It helps determine the energy that moving objects possess and how that energy can be transferred or transformed.

4. Using the Calculator

Tips: Enter mass in kilograms and velocity in meters per second. Both values must be positive numbers. The calculator will compute the kinetic energy in Joules.

5. Frequently Asked Questions (FAQ)

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

Q2: Why is velocity squared in the equation?
A: Velocity is squared because kinetic energy increases with the square of velocity - doubling the velocity quadruples the kinetic energy.

Q3: Can kinetic energy be negative?
A: No, kinetic energy is always positive or zero since both mass and the square of velocity are non-negative quantities.

Q4: How does mass affect kinetic energy?
A: Kinetic energy is directly proportional to mass - doubling the mass doubles the kinetic energy (assuming constant velocity).

Q5: 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.
