Potential Energy Calculation for a Weight Lifter
How is the potential energy gain of a barbell calculated when it is lifted by a weight lifter?
The potential energy gain of an object, such as a barbell, when it is lifted to a certain height is calculated using the formula for potential energy, which is Potential Energy = mass x gravity x height. In this case, we are looking at a weight lifter raising a 90 kg barbell to a height of 1.9 m. Let's dive into the calculation!
Potential Energy Calculation Formula
Potential Energy = mass x gravity x height
Calculation for the 90 kg Barbell
Given values: Mass (m) = 90 kg Gravity (g) = 9.8 m/s² Height (h) = 1.9 m Substitute the values into the formula:Potential Energy = 90 kg x 9.8 m/s² x 1.9 m
After performing the multiplication: Potential Energy = 1670.6 Joules
