You will have 25 minutes to answer a single experimental design question worth 12 points in the FRQ portion of the AP Physics 1 exam. Read the question to determine the relationship being posed, list the quantities to be measured (2:47), develop a procedure to collect that data (4:48), and explain how you would analyze the data collected. (5:46) Good luck!

Question of the Day (7:42) When asked to provide a procedure for an experiment that you have created, what should you avoid doing?

You will have 90 minutes to answer 5 free-response questions. Easiest strategy to implement is to grab the low hanging fruit (0:56). The FRQ questions come in a few varieties: experimental design, qualitative/quantitative translation,(4:02) paragraph argument,(5:14) and two short answer questions.(6:00)

Question of the Day (7:20) Which is a good strategy for answering the paragraph length response FRQ?

On average, you will have 1.8 minutes for each multiple choice question. Episode 31 outlines the best strategies for finding the right answer! Rule out incorrect choices with signage (1:32), know your key words (1:50), know your graphing shortcuts (3:36), and identify the system (4:42).

Question of the Day (6:03) You flip the page and see a graph of force vs time. What should your first thought be?

One of the best strategies for preparing for the Physics 1 exam is knowing what you do not need to memorize. Episode 30 recAPs each unit, with test taking tips, graph reminders and calculator recommendations. Listen for a review of Unit 1 (2:14), 2 (4:01), 3 (6:13), 4 (7:20), 5 (8:28), 6 (9:10), and 7 (9:49)!

Question of the Day (12:13)Asked to find the speed of a 1 kg mass that starts at rest, and is accelerated by a spring, which feature of a force vs position graph could be utilized?

Join Ryan on a daredevil stunt with a bike, go-cart, and skateboard in Episode 29. Objects can be evaluated individually or as part of a larger object we call a “system.” (1:45) Sketch the force diagrams for each object, (2:25) sum the forces on each object and set that net force equal to mass times acceleration. (6:20)

Question of the Day (9:38) If a 1 kg mass is pushed by a 9 N force into a 2 kg mass along a frictionless surface, how fast will they accelerate?

Newton’s 3rd Law is easy to say, but tough to apply. The problem is usually that many people know the catchy phrase, but don’t actually know the meaning of the words in the phrase. (1:23) We explore the gravitational force between you and the Earth. (2:11) But, how does the 3rd law apply to running on a track (2:44) or a wagon being pulled by a tractor? (4:18) We look at all of these scenarios and still had time to discuss what makes a rocket capable of getting into orbit and beyond. (5:26)

The Question of the Day asks: (6:59)

How does the force that the Earth pulls on the International Space Station compare to the amount of force exerted on the Earth by the space station?

Angular momentum is conserved for systems of objects that are rotating. This is true for figure skaters and students on wheel chairs. (1:02) We agree that when determining rotational directions, we use the right hand rule. (2:56) Rotational kinetic energy can change for rotating objects even if their angular momentum is conserved. (5:44)

The Question of the Day asks: (7:15) If you quadruple the moment of inertia for a rotating object, then what outcome can be expected with respect to the angular speed?

Episode 26 focuses on the energy associated with rotating objects. It's important to distinguish between translational motion and rotational motion (1:06). An object that is rotating faster will not be able to be translating as quickly. (2:27) You will need to know the moment of inertia for each object in order to calculate velocity (4:30).

The Question of the Day asks: (7:10)

Assuming they are the same mass and radius, which wheel should you be able to get to rotate with more revolutions per second, a stationary exercise bike or a traditional bike as you ride?
