Kinetic Energy Formula:
| From: | To: |
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.
The calculator uses the kinetic energy formula:
Where:
Explanation: The kinetic energy increases with the square of the velocity, meaning that doubling the speed quadruples the kinetic energy.
Details: Calculating kinetic energy is essential in various fields including physics, engineering, automotive safety, sports science, and energy conservation studies.
Tips: Enter mass in kilograms and velocity in meters per second. All values must be positive numbers greater than zero.
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: 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: Why is velocity squared in the formula?
A: Velocity is squared because kinetic energy depends on the square of the speed, making higher speeds significantly more energetic.
Q4: Can kinetic energy be negative?
A: No, kinetic energy is always positive or zero (when velocity is zero), as both mass and the square of velocity are non-negative.
Q5: 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.
