Question

Calculate the change in PE of 8 million kg of water dropping 50 m over Niagara falls

Answer 1

"4,000,000,000 J" is the "Potential Energy" of water dropping over "Niagara falls".

Step-by-step explanation:

The body possess some energy according to the position of the object that is the when an object is placed at a height it stores some energy it is called "Potential Energy".

Formula used to calculate the "Potential Energy" is
`m* g * h`

Where, "m" is mass of an object given that 8,000,000 kg, "g" is acceleration due to gravity is
`10 m/s^2` and "h" is height of the object is 50 m.

Substitute the given values in the formula,

Potential energy =
`8,000,000*10*50`

Potential energy = 4,000,000,000 J
