Kinetic Energy Formula:
| From: | To: |
Kinetic energy is the energy possessed by an object due to its motion. It depends on both the mass and velocity of the object 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 velocity, meaning doubling the velocity quadruples the kinetic energy, while doubling the mass only doubles the kinetic energy.
Details: Kinetic energy calculations are essential in various fields including automotive safety (crash testing), sports science, mechanical engineering, and understanding energy conservation in physical systems.
Tips: Enter mass in kilograms and velocity in meters per second. Both values must be positive numbers. The calculator will compute the kinetic energy in Joules.
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: 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 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.
Q4: Can kinetic energy be negative?
A: No, kinetic energy is always non-negative since both mass and the square of velocity are always positive or zero.
Q5: How is kinetic energy used in real-world applications?
A: It's used in vehicle safety design, calculating stopping distances, understanding projectile motion, and designing energy-absorbing materials.
