Kinetic Energy To Work Calculator

Introduction

Kinetic energy is the energy associated with the motion of an object. When this kinetic energy is converted into work, it can result in the displacement of an object against a force. Understanding how much work can be done using the kinetic energy of a moving object is vital in various fields.

Formula:

The formula for calculating work ( $W$ ) from kinetic energy ( $K E$ ) is straightforward:

W = 21 m v^{2}

Where:

$W$ represents the work done (in joules or foot-pounds).
$m$ is the mass of the object (in kilograms or pounds).
$v$ is the velocity of the object (in meters per second or feet per second).

How to Use?

Using the Kinetic Energy to Work Calculator involves these steps:

Determine Mass (m): Find the mass of the object in motion. Ensure you use consistent units (kilograms or pounds).
Determine Velocity (v): Measure or determine the velocity of the object in motion. Make sure to use consistent units (meters per second or feet per second).
Plug Values into the Formula: Input the mass (m) and velocity (v) into the formula.
Calculate Work (W): Use the calculator or perform manual calculations to determine the work done.

Example:

Let’s illustrate the calculation with a practical example:

Suppose a car with a mass of 1,200 kilograms is traveling at a velocity of 20 meters per second. Calculate the work done by the car’s kinetic energy.

Using the formula:

W = 21 \times 1, 200 kg \times (20 m/s)^{2} = 240, 000 joules

So, the work done by the car’s kinetic energy is 240,000 joules.
