AP Physics 1: A Quick Word About Equations

As you know, you will be given an Equation Sheet on the day of your exam and that Equation Sheet is yours for the duration of the test. You will see many equations in different forms and it can be hard to recall what is equivalent to what, so we have made a handy chart for you. Here is a tally of a few equations that are equivalent to other equations and where you can find them in this book and on your Equation Sheet.

 Equation(s) Page Location on AP Physics 1 Equations Sheet Big Five #2, #3, #5 93 First three equations in top left Newton’s Second Law 116 Fourth equation below the first three Force of Friction 127 Fifth equation from top Power 149 P=ΔΕ/Δt is the equation on the sheet. Note specifically that the change in energy is the work done, so these two equations are equivalent. Gravitational Force 176 Third equation from the bottom of the second column. Don’t be thrown by the use of absolute value bars; they mean the same thing.
