This is GUSS GUSS has a procedure for solving problems. First, he identifies his Givens. Then he identifies his Unknown. Next, he Selects an equation that relates his Givens and his Unknown, rearranging it for the Unknown if necessary. Finally, he substitutes his Givens into the equation and Solves for his Unknown.
Let’s Practice. . . . Identify the Givens and the Unknown in the following problem: A machine did 240 J of work in 60 s. Calculate its power output.
Let’s Practice. . . . A machine did 240 J of work in 60 s. Calculate its power output. This is not an adequate identification and will not earn you part marks:
Let’s Practice. . . . A machine did 240 J of work in 60 s. Calculate its power output. This will: Note that all Givens have been assigned variables.
Let’s Practice When you Select an equation, you are selecting the equation that contains those variables. The equation that contains W, Dt, and P is:
Let’s Practice This equation does not need to be rearranged. It is already solved for our unknown.
Let’s Practice This equation does not need to be rearranged. It is already solved for our unknown. But what if you needed to solve for W or Dt?
Rearranging Equations If you want to solve for W, you need to get rid of anything on the same side as the W.
Rearranging Equations If you want to solve for W, you need to get rid of anything on the same side as the W. To get rid of a division, use multiplication:
Rearranging Equations If you want to solve for W, you need to get rid of anything on the same side as the W. To get rid of a division, use multiplication:

Rearranging Equations If you want to solve for W, you need to get rid of anything on the same side as the W. To get rid of a division, use multiplication:
Rearranging Equations If you want to solve for Dt, you first need to get it out of the denominator
Rearranging Equations If you want to solve for Dt, you first need to get it out of the denominator and then get rid of anything on the same side as it. To get rid of multiplication, use division.

The Last Step Finally substitute your Givens including units and Solve. Your solution must also contain units!
The Last Step Finally substitute your Givens including units and Solve. Your solution must also contain units! or 4 W since a Joule/second is equal to a Watt.
