What potential energy relative to the Earth’s surface does an apple weighing 150g, hanging on a branch at a height of 3m, have?
| April 9, 2021 | education
These problems: m (the mass of the apple in question) = 150 g (in the SI system m = 0.15 kg); h (the height of the branch on which the apple is located) = 3 m.
Constants: g (acceleration due to gravity) ≈ 10 m / s2.
The potential energy of the apple in question relative to the Earth’s surface is calculated by the formula: En = m * g * h.
Calculation: Ep = 0.15 * 10 * 3 = 4.5 J.
Answer: The potential energy of the apple in question is 4.5 J.
