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

E=98J

#### Explanation:

$m = 10 k g$
$h = 1 m$
$g = + 9.8 \frac{m}{s}$

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
$E = m g h$

$E = 10 \cdot 1 \cdot 9.8$
$E = 98 J$

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