Potential Energy

 is the energy possessed objects because of the influence of his position or his position. Eg bows and arrows drawn if it is then released pull the arrows were going to slide. This is due to bow spring has potential energy. Likewise, apart from the mango fruit stalk will fall, this is because the mango was a gravitational potential energy. The amount of gravitational potential energy of an object can be mathematically formulated as follows : 

Ep = m x g x h
Definition: Ep = potential energy (Joule). m = mass of the object (kg). g = acceleration due to gravity (N / Kg) h = Altitude (meters)
