An object of mass 12 kg is lifted vertically up through a height of 5 m. The gravitational potential energy gained by the object is _____?
- 588 J
- 490 J
- 550 J
- None of these
Explanation
Formula:
Gravitational Potential Energy (GPE) = m × g × h
Where:
m = mass = 12 kg
g = gravitational acceleration = 9.8 m/s²
h = height = 5 m
GPE = 12 × 9.8 × 5 = 588 J
