A A stone 'X' of mass 2 kg is at the height of 2 m from the ground level
Another similar stone 'Y' of mass 4 kg is at the height of 4 m from the ground
level. What is the difference between their potential energy?
un minutes Calculate

120 joule.

Explanation:

Given

For the stone X

Mass (m) = 2 kg

Height (h) = 2 m

Acceleration due to gravity (g) = 10 m/s²

Then we have the formula to calculate the potential energy

P.E 1 = mgh

= 2 * 10*2

= 40 joule

Now for Stone Y

mass (m) = 4 kg

height (h) = 4 m

acceleration due to gravity (g) = 10 m/s²

Now

P. E2 = mgh

= 4 * 10* 4

= 160 joule

Now the difference between their potential energy is

= P. E2 - P. E 1

= 160-40

= 120 joule

Hope it will help you :)

the rocks are classified by the geological process they are formed by. the three main groups of rocks are igneous, metamorphic, and sedimentary. minerals are not they are classified under the chemical classes they are in. these groups include silicates, sulfates and carbonates.
