Energy is the fourth unit.
Assignment in Mathematics
1. Pushing a 10 kg box across level ground with a force of 100 N produces 300 J of work on the box. How far did the force have to be applied?
Stock of Data and Information is a key concept.
Solution
Check for sanity
2. A force of 100 N is applied to lift a 10.0 kg box from the ground to a nearby shelf 2.00 m above the ground. How much effort did it take to raise the box?
Stock of Data and Information is a key concept.

10. Calculate the gravitational potential energy of a 10 kilogram mass at a height of 5 meters above the earth’s surface.
Stock of Data and Information is a key concept.
Solution
Check for sanity
Write down a one- or two-word summary of the physical concept you believe is most important to solving the problem. Describe the aspects of the situation that suggest this physical principle could be used.
Make a list of the numerical data that is provided in the problem description. Don’t forget to mention the units. With a trailing question mark, provide the quantities you’re requested to calculate. A diagram may be included in this phase to help you organize your thoughts about the topic.
I.D. Choose an equation that reflects the main idea of your challenge as well as information from your data set. There’s a chance you’ll need more than one equation.
Solve: If the equation or equations you’ve chosen haven’t already been solved for your unknown, go ahead and do the algebra now. Make sure that each stage has enough description so that a reader can follow along with your job.
Substitute Numerical Data: Once you have an analytic solution, you can get the final result by substituting numerical values into the analytic solution.
Answer the question for a sanity check. “Does this solution make sense in light of the rest of my knowledge?” A back-of-the-envelope calculation with a single significant digit or a unit analysis of the final answer could be used as a sanity check. This stage will vary depending on the underlying information you already have, but it is critical in linking new concepts to what you currently know.
