Kinetic Energy Equation:
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, following the equation KE = (1/2) × m × v².
The calculator uses the kinetic energy equation:
Where:
Explanation: The kinetic energy increases with the square of the velocity, meaning doubling the velocity quadruples the kinetic energy.
Details: Calculating kinetic energy is essential in physics, engineering, and safety analysis. It helps determine stopping distances, impact forces, and energy requirements in mechanical systems.
Tips: Enter mass in kilograms and velocity in meters per second. Both values must be positive numbers.
Q1: What are the units for kinetic energy?
A: The standard unit is Joules (J), which equals 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 (at constant velocity).
Q3: Why is velocity squared in the equation?
A: The squared relationship means velocity has a greater impact on kinetic energy than mass does.
Q4: 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 state.
Q5: Can kinetic energy be negative?
A: No, since both mass and velocity squared are always positive, kinetic energy is always positive or zero.
