Introductory worksheet gives students practice drawing Free Body Diagrams for a simple situation (huskies pulling dog sled) involving 2 vertical forces and 3 horizontal forces. Students write an expression for net force along each axis using the correct symbols/abbreviations and apply the 2nd law to find the acceleration. Follow up questions use kinematic formulas to describe the resulting motion.

Using proportional reasoning lets us find quantitative and qualitative answers to Physics and Math problems in a fast and easy way. This 4 page tutorial explains a three step process for approaching these problems, and also has 6 completely worked examples to help the student become a master at solving proportional reasoning problems. Great prep for the AP Physics and other standardized Physics exams.

This tutorial and mini-worksheet explains the rationale for and the steps for creating a Free Body Diagram (FBD). Includes determining the contact and non-contact forces at play, and labeling forces. A short, but challenging, exercise lets students create 2 FBDs so they can practice the steps, and see how the choice of system changes a FBD.

A 1 page review of Newton's first and second laws. Students fill in the blanks using a word bank. Good warm-up activity with a partner or small group. Complete solution included.

This is a quick 1 page reference sheet that contains 20 SI prefixes, the 7 root SI units, and an explanation of how prefixes and units combine to give re-sized units. Also defines Liters and millilters in terms of SI units. A very handy reference sheet.
