          AP Physics 1 Class Projects - Windows Applications - Version 2022 ©

Welcome to the AP Physics 1 Class Projects site. We designed several class projects of great value to physics teachers and students. Most projects are based on AP Physics problems that were given to the students in official AP Physics exams. We transformed the different problems into comprehensive learning activities that are not only motivating, but also of high academic value. For instance, the Bouncing Ball project, is a superb activity in mechanics that requires about 4 hours of intense work, and the application of concepts in projectile motion, conservation of momentum, and conservation of energy.

It is recommended that teachers give a different set of values for the students to use in each project. One good thing is that each project includes a tutorial, which explains in detail the work that needs to be done. In addition, each project also includes a Windows application that generates in seconds the answer keys of all the projects that were given to an entire class. Therefore, teachers will take just one minute or so to grade each project. We made these educational products very affordable to teachers. For just $14.95 you can buy in Teachers Pay Teachers a class project that will give your students an unforgettable learning experience. You can choose what output with the answer keys is more convenient to you. In some projects the answer keys are shown on the computer screen. In other peojects, the output is a textfile, which you can edit and send to the printer.

The projects available are the following:

                        The Bouncing Ball Class Project



      A ball is released from a point above an inclined plane. The following information is known:

        the mass m of the ball
        the height
         h above the inclined plane where the ball is released.
        The angle of inclination
         θ the plane makes with the horizontal.
        The value of gravity
         g

      The ball is allowed to bounce 5 or more times down along the inclined plane. For each bounce, each student has to calculate several values. The first bounce is from point P1 to point P2, the second bounce from point P2 to point P3, the third bounce from P3 to point P4, and so on. All the bounces are perfectly elastic, thus, the ball experiences no loss of kinetic energy during each collision with the plane. And, of course, momentum is always conserved. Students will find 10 values in each bounce. For instance, during the second bounce between points P2 and P3, the students will calculate the following quantities (note that in this bounce the first point is P2 and the second point is P3):

        The velocity of the ball at the first point - Variable VEL(P2)
        The velocity of the ball at the second point - Variable VEL(P3)
        The time the ball takes to travel between the two points - T
        The distance traveled along the plane between the two points - Variable L
        The horizontal velocity immediately after beginning the bounce - Variable Vx
        The vertical velocity immediately after beginning the bounce - Variable Vy
        The angle the ball makes with the vertical right before it bounces from the first point - Variable Beta
        The angle the ball makes with the inclined plane right before or right after it bounces from the first point - Variable INC
        The angle the ball makes with the horizontal immediately after it bounces from the first point - Variable ALPHA
        Kinetic energy of the ball at the first point - Variable KE

               The Inclined Plane and the Spring Class Project

      the inclined plane and the spring



      A spring is placed at the bottom of an inclined plane. Starting from rest, a block of mass M is allowed to slide down the frictionless plane. After traveling the distance d down along the plane, the block starts compressing the spring. One good question to ask is: where does the block have the greatest speed from the moment it starts sliding to the moment it is stopped by the spring?

      The following values need to be entered:

        the mass M of the block.
        the force constant K of the spring.
        The initial separation
         d between the block and the spring.
        The angle of inclination
         θ of the plane.
        The value of gravity
         g.

      The computer will estimate these values:

        The acceleration of the block
        The velocity at the instant the block strikes the spring
        The maximum length L the spring is compressed by the block

      From the moment the moving block starts compressing the spring, for every centimeter the spring is compressed, and until the block stops, the computer will calculate the following quantities:

        Speed of the block
        Kinetic Energy of the block
        Net Force acting on the block
        Acceleration of the block
        Potential Energy stored in the spring

      All the results will be printed on the screen.

      The Inclined Plane and the Spring Project: The data for one student is entered on the screen in a few seconds, and the answer key is printed on the screen right away. It includes a tutorial that explains step by step the solution of this problem.

                        The Vertical Spring Class Project

      A light vertical spring has an original unstretched length Lo. A block of mass M is carefully attached to its lower end, and the block comes to rest when the new length of the spring is L. Finally, the block is pulled down the distance X, and then it is released, causing the block to oscillate up and down from the equilibrium line.

      The application will ask to enter the following data:

        the mass M of the block.
        the initial length of the spring
         Lo.
        the new length of the spring
         L.
        the additional length
         x the spring is stretched.
        The value of gravity
         g.

      The following quantities will be calculated:

        the force constant K of the spring.
        the frequency
         f.
        the period
         T.
        the maximum speed of the block
         V.
        the maximum acceleration
         a of the block.

      For convenience, the student will assume that the block has zero Potential Energy PE when it is located at the lowest point of each oscillation. Starting at the lowest point, for every centimeter the block moves, the following values will be calculated:

        Potential Energy of the block
        Kinetic Energy of the block
        Potential Energy stored in the spring
        Velocity of the block
        Acceleration of the block

      It is recommended that teachers give a different set of values to each student. To practice graphing, the students will do the graph Displacement ( -x to +x ) vs. PE (block), KE (block), PE (spring), and TE.

      The Vertical Spring Project 1: The data for one student is entered on the screen in a few seconds, and the answer key is printed on the screen and also sent to a textfile right away. It includes a tutorial that explains step by step the solution of this problem.

         L of the string.
        the angle
         θ with the vertical the pensulum is released.

         g.

      The computer will find:

        Period and Frequency
        The Maximum Velocity
        Maximum Kinetic Energy


      For every degree the pendulum moves, the following values are calculated:

        Velocity
        Kinetic Energy KE
        Potential Energy PE
        Total Energy TE
        Centrifugal Force
        Tension in the string

                        The Block on the Sphere Class Project



      A small block is placed on top of a large sphere. The block is then touched very softly, causing it to slide, starting from rest, on the frictionless surface of the sphere. Eventually, the block loses contact with the surface of the sphere and becomes a projectile.

      The application will ask to enter the following data:

        the mass m of the block.
        the radius
         R of the sphere.
        The value of gravity
         g.

      From the moment the block is released on top of the sphere, to the moment the block becomes a projectile after traveling an arc in degrees that needs to be estimated, for every 5-degree segment the block slides, the computer will calculate the following quantities:

        the Potential Energy PE (PE of the block is zero at the center of the sphere).
        the Kinetic Energy
         KE of the block.
        the Total Energy
         TE.
        the Velocity
         V of the block.
        the linear acceleration
         a.
        the Centrifugal Force
         F.
