Kinetic Energy Formula:
From: | To: |
Definition: This calculator computes the kinetic energy of a moving object based on its mass and velocity.
Purpose: It helps students, physicists, and engineers determine the energy possessed by a body due to its motion.
The calculator uses the formula:
Where:
Explanation: The kinetic energy is proportional to the mass of the object and the square of its velocity.
Details: Kinetic energy calculations are essential in physics, engineering, safety analysis, and understanding motion dynamics.
Tips: Enter the mass in kilograms and velocity in meters per second. All values must be > 0.
Q1: What are the units of kinetic energy?
A: The SI unit is Joules (J), where 1 J = 1 kg·m²/s².
Q2: Why is velocity squared in the formula?
A: Because kinetic energy increases with the square of velocity - doubling speed quadruples the energy.
Q3: What's a typical kinetic energy for everyday objects?
A: A 1kg object moving at 1m/s has 0.5J; a car at 30m/s (108km/h) has about 225,000J (for 1000kg mass).
Q4: How does mass affect kinetic energy?
A: Kinetic energy is directly proportional to mass - double the mass, double the energy at same velocity.
Q5: What's the difference between kinetic and potential energy?
A: Kinetic is energy of motion, potential is stored energy due to position or state.
