\[
EL = \frac{1}{2} M Vi^2 - \frac{1}{2} M Vf^2
\]
Where:
\( EL \) is the energy loss in joules
\( M \) is the mass of the object in kilograms
\( Vi \) is the initial velocity in meters per second
\( Vf \) is the final velocity in meters per second
Definition
Energy Loss: Defined as any negative change in energy of a system. This energy loss can be through heat, radiation, movement, or friction. In this context, we are specifically looking at the kinetic energy loss of a moving object.
Example
Let's say the mass of the object (M) is 10 kg, the initial velocity (Vi) is 20 m/s, and the final velocity (Vf) is 10 m/s. Using the formula:
