# ap physics 1 algebra based 2015 free response questions answers

The student writes down the following two equations, each of which includes a positive constant C1 or C2 with appropriate units. Which equation better mathematically models this experiment? Briefly explain why the equation you selected is plausible and why the other equation is not plausible. Draw graphs of velocity and acceleration of an object experiencing a constant torque. Combine the relevant equations torque, angular kinematics to solve for the rotational inertia of the disk.

Draw graphs of velocity and acceleration for an object experiencing a changing torque. Determine which equation correctly describes the behavior of the disk over time and explain why. In the diagrams below, those dots are labeled P and Q.

At the instant shown, dot P has maximum displacement and dot Q has zero displacement from equilibrium. At each of the dots P and Q, draw an arrow indicating the direction of the instantaneous velocity of that dot.

At each of the dots P and Q, draw an arrow indicating the direction of the instantaneous acceleration of that dot. For simplicity, dot Q is not shown. Draw arrows to represent the instantaneous velocity of a point on a wave that's at maximum displacement, and a point on a wave that's at zero displacement.

Draw arrows to represent the instantaneous acceleration of a point on a wave that's at maximum displacement, and a point on a wave that's at zero displacement.

How far does a single point on the wave travel during one period? The block is oscillating with period TP and amplitude AP about the spring's equilibrium position x0. A second block Q of mass 2m is then dropped from rest and lands on block P at the instant it passes through the equilibrium position, as shown above. How does the period of the spring-mass system's oscillation change after the second block is dropped onto the first expressed as a numerical ratio? How does the amplitude of the spring-mass system's oscillation change after the second block is dropped onto the first expressed as a numerical ratio?

Use concepts of simple harmonic motion, collisions, and conservation of energy to write a paragraph-length explanation of your answers to parts a and b. In circuit 1 a dingle lightbulb is connected to the battery. In circuits 2 and 3, two lightbulbs are connected to the battery in different ways, as shown. The lightbulbs are labeled A-E.

If any of the lightbulbs have the same potential difference across them, state that explicitly. Briefly explain how you determined your ranking. In which circuit will the battery run out of usable energy first? In which circuit will the battery run out of usable energy last? In a clear, coherent, paragraph-length response that may also contain equations and drawings, explain your reasoning. Order the lightbulbs from largest potential difference voltage drop , and briefly explain why you ordered them that way.

Which circuit uses energy at a faster rate? Which circuit uses energy at a slower rate? Explain your answer in a more detailed way. In your diagram, indicate each quantity that would be measured and draw or state what equipment would be used to measure each quantity.

A physics class consisting of six lab groups wants to test the hypothesis that the coefficient of static friction between the board and the block equals the coefficient of kinetic friction between the board and the block.

Each group determines the coefficients of static and kientic friction between the board and the block. The groups' results are shown below, with class averages indicated in the bottom row. Briefly justify your reasoning. The mass of the block-disk system is twice the mass of the original block. Does the coefficient of static friction between the bottom of the block and the board increase, decrease, or remain the same when the disk is added to the block?

Briefly state your reasoning. Design an experiment to find the coefficient of static friction between two surfaces. Include a diagram, where you show all the quantities that you will measure in the experiment, and a detailed procedure. The free-response questions from past AP Physics B exam questions are still available. AP Central.

Now, the AP Physics 1 exam will have 50 multiple-choice questions over 90 minutes and five free response questions over 90 minutes. The AP Physics 2 exam will follow the same format, but will limit the number of free response questions to four, cutting out the third short answer question. While these changes may seem significant, they will ultimately leave students better prepared for college physics. Working with AP Physics B tutors can be of great help in this process as well.

By spreading the acquisition of knowledge over two years, students will be more knowledgeable, prepared, and confident in their abilities to perform advanced physics. Louis Tucson Washington DC.

Sphere B is given an initial horizontal velocity of magnitude v0 and travels a horizontal distance D before it reaches the ground. The spheres reach the ground at the same time t f , even though sphere B has more distance to cover before landing. Air resistance is negligible.
