Question

How do you calculate the potential 10-kg sack of groceries on a shelf 1 m above the floor?

Answer 1

E=98J

Explanation:

`m=10kg`
`h=1m`
`g=+9.8m/s`

now we know that potential energy is the mechanical energy of a body/object possessed by the virtue of its position.enter link description here

Now, you can see in the image the formulae of potential energy.
So,now
`E=mgh`

`E=10*1*9.8`
`E=98J`

Hence,we say the gravitational potential energy the object is 98`J`.
