11. PHP Program to find Mechanical Energy of a particle is given by e=mgh+(1/2)mv^2.
How does this program work?
- In this program you will learn about how to calculate Mechanical Energy using PHP.
- This program requires the user inputs Mass ,displacement and velocity of an object.
- In this program First we calculate Potential Energy and Kinetic Energy.
- After that we will be find Mechanical energy by the combination of kinetic energy and potential energy.
Here is the code

$K = 0.5 * $m * $v * $v; //To calculate Kinetic energy(K.E = 1/2mv^2)
$Me = $P + $K; //To calculate Mechanical energy(M.E = P.E+K.E)
echo "Potential energy = ".$P."J" ;
echo "Kinetic energy = ".$K ."J";
echo "Mechanical energy = ".$Me."J";
return 0;
