A 2-kg ball is held 4 m above the ground. Relative to the ground its potential energy is Group of answer choices8 J80 J32 J6 J
Question
Solution 1
The potential energy (PE) of an object can be calculated using the formula:
PE = mgh
where: m = mass of the object (in kg) g = acceleration due to gravity (on Earth, it's approximately 9.8 m/s²) h = height above the ground (in m)
Given in the problem: m = 2 kg g = 9.8 m/s² h = 4 m
