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, and is a fundamental concept in physics and engineering.

2. How Does the Calculator Work?

The calculator uses the kinetic energy formula:

Where:

• \( KE \) — Kinetic energy (joules)
• \( m \) — Mass of the object (kg)
• \( v \) — Velocity of the object (m/s)

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

3. Importance of Kinetic Energy Calculation

Details: Calculating kinetic energy is essential in various fields including physics, engineering, automotive safety, 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.

5. Frequently Asked Questions (FAQ)

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

Q2: How does mass affect kinetic energy?
A: Kinetic energy is directly proportional to mass - doubling the mass doubles the kinetic energy (assuming constant velocity).

Q3: How does velocity affect kinetic energy?
A: Kinetic energy is proportional to the square of velocity - doubling the velocity quadruples the 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 based on an object's position or state.

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 non-negative.
