Kinetic Energy Formula:
| From: | To: |
The kinetic energy formula calculates the energy possessed by an object due to its motion. It is a fundamental concept in physics that describes how much work an object can do by virtue of its velocity.
The calculator uses the kinetic energy equation:
Where:
Explanation: The equation shows that kinetic energy is proportional to the mass of the object and the square of its velocity.
Details: Kinetic energy calculations are essential in various fields including mechanics, engineering, automotive safety, sports science, and energy conservation studies.
Tips: Enter mass in kilograms and velocity in meters per second. Both values must be positive numbers (mass > 0, velocity ≥ 0).
Q1: What are the units for 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 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 positive or zero since mass is always positive and velocity is squared.
Q4: How does mass affect kinetic energy?
A: Kinetic energy is directly proportional to mass - doubling the mass doubles the kinetic energy if velocity remains constant.
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.
