Q & A
What is the format of the AP Physics 1 exam?
-The AP Physics 1 exam consists of two parts: multiple choice and free response, with equal weight and time allocation. The multiple choice section has 50 questions, including 5 multi-select questions, to be completed in 90 minutes, and is worth 50% of the score. The free response section also consists of 5 questions to be completed in 90 minutes, contributing another 50% to the total score.
What types of questions can be expected in the free response section of the AP Physics 1 exam?
-The free response section includes five types of questions: experimental design, qualitative quantitative translation, paragraph argument short answer, general short answer, and sketching or plotting graphs. The experimental design and qualitative quantitative translation questions are worth 12 points each and contain 3 to 5 parts, while the paragraph argument short answer and general short answer questions are worth 7 points and consist of 1 to 3 parts.
How does the exam assess a student's ability to design and describe a scientific investigation?
-The experimental design question in the free response section is designed to assess a student's ability to design and describe a scientific investigation. It typically includes 3 to 5 parts and requires students to develop a procedure, analyze data, identify patterns, and explain phenomena within a given context.
What is the significance of the formula chart provided during the AP Physics 1 exam?
-The formula chart provided during the exam is a valuable tool for students. It contains essential formulas, constants, unit symbols, and prefixes. Students can use it to explain relationships in their responses, even when not directly asked to perform calculations. The chart also reminds students of assumptions like the inertial reference frame and the neglect of air resistance, unless stated otherwise.
What is the role of task verbs in the AP Physics 1 free response questions?
-Task verbs in the free response questions guide students on what is expected of them in their answers. For example, 'plot' and 'sketch' direct students to create different types of graphs, 'calculate' requires showing all mathematical steps for a final answer, 'derive' involves creating an equation with variables, and 'determine' is about making a decision or conclusion without necessarily showing work.
Why should a smaller mass dart be used to achieve the furthest distance in the described experiment?
-A smaller mass dart should be used because, given the same force exerted through the tube, a smaller mass will result in a higher acceleration and thus a greater horizontal velocity upon exit. Since the mass of the dart does not affect its flight once it has left the tube, a smaller mass will travel the furthest distance due to its higher exit velocity.
Does the provided equation x = m*h^2*g/(f*g*l^2) correctly represent the relationship between the variables for the horizontal distance x in the dart experiment?
-No, the equation does not correctly represent the expected relationship. It suggests a direct proportionality between mass (m) and distance (x), which contradicts the qualitative reasoning that a smaller mass should result in a greater distance. The mass term should be in the denominator to reflect an inverse relationship, and the equation's units on the right side do not match the required dimensions for distance.
How should students graph data to linearize the equation for determining the height of the tube in the dart experiment?
-To linearize the data, students should graph the square of the horizontal distance (x^2) on the y-axis and the constant force (f) on the x-axis. This setup mirrors the equation h = (mg*x^2)/(4*f*l) and transforms it into a linear form, where the slope of the graph represents the constant (4*l*h)/mg, allowing for the determination of the tube's height (h).
What is the expected change in angular velocity when the radius of rotation decreases in the amusement park ride scenario?
-The angular velocity is expected to increase when the radius of rotation decreases. This is because the rotational inertia decreases while the angular momentum remains constant due to the absence of external torque. A decrease in rotational inertia with constant angular momentum results in an increase in angular velocity.
How does the rotational kinetic energy of the amusement park ride change when the riders are pulled inwards to a smaller radius?
-The rotational kinetic energy of the ride increases when the riders are pulled inwards to a smaller radius. This is because work is done by the force pulling the riders inwards, which increases the system's kinetic energy without changing the angular momentum, as there is no net torque acting on the system.
What is the main takeaway for students when approaching the multiple choice section of the AP Physics 1 exam?
-Students should not leave any questions blank and should practice good pacing by answering questions they know first and skipping those that require more time. They should return to skipped questions later if time permits and make educated guesses if necessary. It's also important to read all parts of a question before starting to answer and to be consistent in their responses.

Two full-length free response questions will be practiced, an experimental design question and a qualitative-quantitative translation question. The speaker also provides information about the exam date, what to bring, and the use of the formula chart provided during the exam.
🧠 Understanding Free Response Question Types
The speaker delves into the five types of free response questions that will be encountered on the AP Physics 1 exam. These include the experimental design question, the qualitative-quantitative translation question, the paragraph argument short answer question, and two general short answer questions. Each question type is briefly explained, highlighting the importance of understanding the task verbs and the expected responses. The speaker emphasizes the need to use the formula chart effectively, even when not performing calculations, to explain relationships and justify answers.
📊 Strategies for Answering Questions
The speaker provides strategies for answering different types of questions on the exam. She explains the difference between plotting and sketching, as well as between calculating, deriving, and determining. The speaker advises viewers to underline or circle important verbs in the question stem to understand the actions required. She also discusses the importance of understanding the relationships between variables and constants when answering free response questions.
🚀 Free Response Question 1: Experimental Design
The speaker presents the first free response question, which is an experimental design question involving a dart moving through a tube and its horizontal distance upon exiting. The question is broken down into parts, each requiring a specific type of response, from choosing the appropriate mass for the dart to analyzing a provided equation's agreement with qualitative reasoning. The speaker guides viewers through the process of determining the height of the tube using linear regression analysis and plotting data to find the linearized relationship between variables.
🎢 Free Response Question 2: Qualitative-Quantitative Translation
The second free response question involves an amusement park ride with changing radii and the effects on angular velocity and rotational kinetic energy. The speaker explains how to approach the question without mathematical derivation, focusing on physical reasoning and the expected changes in angular velocity and kinetic energy.
