A Research Study On Nhs Pendulum Lab

When we started the project, we had to first draw a blueprint of our roller coaster with an appropriate scale factor. Our group chose to have a 1:10 scale factor where 1 centimeter on the paper would become 10 centimeters on the wall. Our group decided on having 3 hills and one loop. We had decided to start with the loop because the marble would have the most kinetic energy to let it go through the loop with ease. Then we would have the 3 hills afterwards because a hill requires less kinetic energy to allow the marble to

13. Next, adjust tension back to high, change it to a fixed end, pulse, and reset the wave. Send a pulse and when it has traveled about half way to the end send a second. When the first pulse is on its way back and the second is moving toward it pause the simulation and then step it while you observe the

A 15 kg uniform disk of radius R = 0.25 m has a string wrapped around it, and a m = 3 kg weight is hanging on the string. The system of the weight and disk is released from rest.

An ideal pendulum is shown swinging in the diagram below. As the pendulum swings freely from A to B as shown in the diagram below:

Finally, a pendulum is very similar to a guillotine in its design and function where gravity does the killing in both cases (Pg 50).

Hypothesis: If the stiffness of the spring increase, then the displacement of the bob from the equilibrium point will decrease proportionally, since as the spring getter stiffer, there is more tension that held the bob from the spring, which decrease the amount of distance that the bob travels from the equilibrium point. A stiffer spring also increase the natural frequency, so when we increase the stiffness of the spring, the period of oscillation is shorter, the amplitude is smaller and the speed max is smaller, which shows less displacement.

At first I was unsure on how these were different but after using the lab program and following the instructions I can now see that different balances are needed for difference situations. Some that may require a more precise measurement where as others may not need such accurate measurements.

People sometimes engage in activities and are unaware that such activity involves physics. Physics is all around. For instance, you may go to Six Flags and do not analyze how physics helps the machines you ride in operate. Have you ever asked yourself how a roller coaster works? Would roller coasters safely run without the knowledge that physics offers us? The answer is no. Roller coasters are driven by physics; it mobilizes and gives its riders amusement through forces such as inertia, gravitation, and centripetal forces and utilizes different types of energies such as potential and kinetic energy. Physics is what makes roller coasters safe and effective. It is not only the high speed of the trains of a roller coaster that makes the

In our graph of the average times it took the marbles to go down the roller coaster, it is shown that there is an optimal or best amount of mass for the marble to be in order to have the fastest time. Marble four, or the second largest marble, had the fastest average time. As the mass of the marbles increased, their time increased as well, making marble five slower than marble four because its mass was greater than the optimum mass. Marble one, two, and three were also slower than marble four because its mass was less than the optimum mass.

For a thrilling experience in a rollercoaster ride, there is a wealth of physics involved. A part of the physics of a rollercoaster includes the physics of work and energy. The Redback is a pendulum type ride at Aussie World that includes many types of physics concepts. These concepts include the conversion of gravitational potential energy to kinetic energy, G-force, the conservation of energy and simple harmonic motion. The calculations of the ride of the Redback can be seen in Appendix B.

We had to make a safe, but thrilling, roller coaster for Six Flags Great Adventure. We had to sell the idea to the top engineers. We made a roller coaster that was safe, and fun at the same time. We put toilet paper rolls over the track so the marble won’t fall out. We also put toilet paper rolls where there’s a possibility for the marble to come flying out. We added a loop and a sharp turn, which ends with tape slowing the marble down to a complete stop at the end. Our prototype was successful because the marble made it to the end. All we had to add was toilet paper rolls in places where it would fall out, and put the sharp turn under the meter stick instead of over it. We made the ending slower so the marble doesn’t crash into the cup. This

A pendulum is a bob suspended by a string from a fixed point and behaves in an oscillating manner. When released from an angle away from its equilibrium, it swings side-to-side in a periodic motion. The time it takes to complete one full swing is considered the period and the purpose of this investigation is to discover the effect of the string length on the period of the pendulum. This will be accomplished by recording and analyzing data with the use of data tables and graphs.

A simple pendulum consists of a mass that is attached to a string of length ‘L’ that is fixed to a point, in this case, a cork suspended by a clamp stand. This allows the mass to be suspended vertically downwards and allows it to be displayed at an angle that it swings. A period ‘T’ of oscillation is the time required for one complete swing. For this to happen ideally its mass must swing from an angle that is
