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 is required to accelerate an object from rest to its current velocity.
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: Kinetic energy calculations are essential in various fields including physics, 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 greater than zero for accurate calculation.
Q1: What are the units for kinetic energy?
A: The standard unit for kinetic energy is joules (J) in the SI system.
Q2: How does mass affect kinetic energy?
A: Kinetic energy is directly proportional to mass - doubling the mass doubles the kinetic energy (assuming constant velocity).
Q3: Why is velocity squared in the formula?
A: Velocity is squared because the energy required to accelerate an object increases with the square of its speed.
Q4: Can kinetic energy be negative?
A: No, kinetic energy is always positive or zero (when velocity is zero) since both mass and velocity squared are always positive.
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.
