1. What is the Kinetic Energy Formula?

The kinetic energy formula calculates the energy possessed by an object due to its motion. It is a fundamental concept in physics that quantifies the work needed to accelerate an object from rest to its current velocity.

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 the square of its velocity.

3. Importance of Kinetic Energy Calculation

Details: Calculating kinetic energy is essential in physics, engineering, and various practical applications including vehicle safety design, sports science, and energy conservation calculations.

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 for kinetic energy?
A: The SI unit for kinetic energy is joules (J), where 1 J = 1 kg·m²/s².

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

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

Q4: How does mass affect kinetic energy?
A: Kinetic energy is directly proportional to mass - doubling the mass doubles the kinetic energy at the same velocity.

Q5: What's the difference between kinetic and potential energy?
A: Kinetic energy is energy of motion, while potential energy is stored energy based on position or configuration.
