Find The Potential Energy Of A Boy Mass 10kg Standing On A Building Floor Of 10 Metres Above Ground Level. 10*10*10 =1000
Looks about right, if you use g=10 m/s^2

What is the answer
Well, it seems like you've already done the math! However, I must clarify that the equation you provided is not the one to calculate potential energy. The formula for potential energy is given by PE = mgh, where m is the mass of the boy (10 kg), g is the acceleration due to gravity (approximately 9.8 m/s²), and h is the height (10 meters). So let's calculate the potential energy:
PE = (10 kg) * (9.8 m/s²) * (10 m)
PE = 980 J
So, the potential energy of the boy standing on the building floor is 980 Joules. That's quite an energetic boy!
To calculate the potential energy of an object, you need to use the formula: potential energy (PE) = mass (m) * acceleration due to gravity (g) * height (h).
In this case, the mass of the boy is given as 10 kg, the height of the building floor is 10 meters, and the acceleration due to gravity is approximately 9.8 m/s^2.
Using the given values, we can calculate the potential energy using the formula:
PE = m * g * h
PE = 10 kg * 9.8 m/s^2 * 10 m
PE = 980 joules
Therefore, the potential energy of the boy standing on the building floor of 10 meters above ground level is 980 joules.
