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 measured in joules (J) in the International System of Units.

2. How Does the Calculator Work?

The calculator uses the kinetic energy formula:

Where:

• \( KE \) — Kinetic Energy (J)
• \( m \) — 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. It also increases linearly with mass.

3. Importance of Kinetic Energy Calculation

Details: Calculating kinetic energy is essential in physics, engineering, and safety analysis. It helps determine the energy involved in collisions, design safety systems, and understand energy conservation in mechanical systems.

4. Using the Calculator

Tips: Enter mass in kilograms and velocity in meters per second. Both values must be valid (mass > 0, velocity ≥ 0). The calculator will compute the kinetic energy in joules.

5. Frequently Asked Questions (FAQ)

Q1: 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.

Q2: Why is velocity squared in the kinetic energy formula?
A: Velocity is squared because the work needed to accelerate an object increases with the square of the final velocity.

Q3: What are typical kinetic energy values?
A: Kinetic energy varies widely - from small values for slow-moving objects to very large values for vehicles at high speeds.

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

Q5: How does kinetic energy relate to momentum?
A: Both involve mass and velocity, but kinetic energy is a scalar quantity while momentum is a vector quantity.
