Given data:
Mass of oyster (m) = 25 g,
= 0.025 kg (<em> since 1 Kg = 1000 g)</em>
Height of oyster (h) = 11 m,
determine gravitational potential energy (GPE) = ?
Gravitational potential energy is energy of an object possesses because of its position on the earth. The amount of gravitational potential energy of an object on earth depends on its<em> mass</em> and<em> height </em>from the earth.
Mathematically,
GPE = m. g. h <em>Joules</em>
<em> Where, </em>
<em> </em>GPE =<em> </em>gravitational potential energy,
<em> </em> m = mass of object in Kg,
g = gravitational force in m/s², g = 9.8 m/s²
h = height of the object in meters,
Now substituting all the values in the equation GPE
GPE = 0.025 Kg × 9.8 m/s² × 11 m
= 2.695 J
Gravitational potential energy of the oyster is 2.695 J
