Hi everyone. I am Dan Fullerton. Welcome back to Educator.com. 0000
What we are going to do now is we are going to work through a series of worksheets that are fairly basic level problems, not quite at the level of the AP Physics exam that we are preparing you for, but it gives you an idea if you have the basic concepts down. 0004
If these go well, it is great to keep moving on, but if you struggle with these, it is probably an excellent opportunity to go back to some of the previous videos and review them and make sure you get the basic concepts down. 0018
We will just do the first page of each of these sheets. 0029
Starting with metric estimation -- and you can find a link to download it at the bottom of the page -- we will look at Number 1. 0032
What is the approximate width of a person's little finger? 0040
A little finger is about 1 cm wide, which could be 0.01 m. 0042
Number 2 -- The approximate mass of an automobile...?0051
A hundred kilograms is about the mass of a pretty big person -- 106 kg is humongous, so let us go with 103 kg, or about a 1000 kg or on the order of 2,000 lbs. 0055
Draw a penny, measure its diameter, and you should find out that again, you are starting to talk in the range of about 1 cm, which is 10-2 m. 0074
Number 4 -- We are going to drop an egg from a third-story window and the distance the egg falls from the window to the ground is closest to...?0085
If we assume that each story is about 3 m or 3 yards in the English system -- they are pretty close to each other -- that is going to be 9 m or 10 m for 3 stories, so 101 m, which is pretty close. 0094
The approximate height of a 12 oz. can of root beer...?0110
A root beer is about that tall and compared to a meter, it is about 1/10 of a meter or somewhere in that ballpark, so I would say that it is about 0.13 m or Answer 2. 0113
The book features an effective, 5-step plan to guide your preparation program and help you build the skills, knowledge, and test-taking confidence you need to succeed. This fully revised edition covers the latest course syllabus and matches the new exam. It also includes access to McGraw-Hill Education’s AP Planner app, which will enable you to customize your own study schedule on your mobile device. It includes a full-length practice AP Physics 1 exam and 3 separate study plans to fit your learning style.
This book is written by our very own Professor Fullerton and features more than 600 worked-out problems with full solutions and deeper understanding questions. AP Physics 1 Essentials covers all major topics included in the AP Physics 1 course, including: kinematics, dynamics, momentum, impulse, gravity, uniform circular motion, rotation, work, energy, power, mechanical waves, sound, electrostatics, and circuits.
