🔍 Key Concepts

• Formula for potential energy in terms of weight and height (in English units): PE = weight × height, giving units of foot-pounds (ft-lb). • Recognize that the weight is already given in pounds, so you do NOT need to convert mass to weight for the ft-lb part. • Match the calculated ft-lb value to the closest numerical choice before worrying about the kg-m values.

💭 Think About

• First, ignore the metric numbers and focus only on the English units: with a weight of 10 lb at a height of 10 ft, what simple multiplication would you do? • After you compute the ft-lb, look through the answer choices and see which one has that same ft-lb value. • Ask yourself: does potential energy go up linearly with height, weight, or both in this basic formula?

✅ Before You Answer

• Be sure you are using weight (lb), not mass (kg), in the English-unit calculation. • Confirm your units: the result should be in ft-lb, not ft or lb alone. • Once you have the ft-lb value, verify that exactly one answer choice has that same ft-lb number before you consider the kg-m side.
