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.
The calculator uses the kinetic energy formula:
Where:
Explanation: The formula shows that kinetic energy increases with the square of velocity, meaning doubling speed quadruples kinetic energy.
Details: Calculating kinetic energy is essential in physics, engineering, and various real-world applications including vehicle safety design, sports science, and energy conservation calculations.
Tips: Enter mass in kilograms and velocity in meters per second. All values must be valid (mass > 0, velocity > 0).
Q1: What are the units of kinetic energy?
A: The SI unit for kinetic energy is the Joule (J), which equals 1 kg·m²/s².
Q2: How does kinetic energy relate to work?
A: The work-energy theorem states that the net work done on an object equals its change in kinetic energy.
Q3: 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.
Q4: Can kinetic energy be negative?
A: No, kinetic energy is always positive or zero since both mass and velocity squared are non-negative.
Q5: How is kinetic energy used in real-world applications?
A: It's used in calculating stopping distances for vehicles, designing safety equipment, analyzing sports performance, and in renewable energy systems like wind turbines.
