IB Physics Internal Assessment Andy Tang Research Question In this internal assessment, I am given a cantilever to find the physical properties of it. I decide to investigate the relationship between the force I act on one side of the cantilever and the maximum acceleration the tail can reach. This experiment will be also showing the elasticity of the cantilever. Since I pull down one side of it and fixed the other side, when I cut the string, it will bounce up and down until all the internal
Chee Yong Hui 6.5 Domino Effect IA Investigate the effect of the distance between each domino on the time taken for all the dominoes to fall Independent Variable: Distance, d/cm, between each domino. The distance d/cm is measured between the middle of one domino to the middle of the next domino Dependent Variable: Time taken for all the dominoes to be toppled to the ground. The timing will start when the 1st domino is hit by a metal ball and it will stop when the last domino falls completely
AIM To find the acceleration of an object when falling down from a height in the presence of earth’s gravitational field, which is also known as free fall. Air resistance is neglected in this experiment. THEORY As an object is released from a height from the ground under the influence of the Earth’s gravitational force, the object will always fall under a constant rate of acceleration. Unlike in space, where object will just float around after being released, object falling on Earth will always
Calculus IA Section 2, Part B 4. A particle moves along the x-axis with position at time t given by x (t) = e-t sin t for 0 ≤ t ≤ 2π. (a) Find the time t at which the particle is farthest to the left. Justify your answer. Answer: x’ (t) =e-t sin t + e-t cos t = e¬¬¬-t (cos t – sin t); x’ (t) = 0 when cos t = sin t. Therefore, x’ (t) = 0 on 0 ≤ t ≤ 2 π for t = π/4 and t = 5 π/4. For the absolute minimum are at t = 0, π/4, 5 π/4 and 2 π. The particle is farthest to the left when t = 5 π/4. (b) Find

Mike was also a man who fled to Cuba UNITED States when she was fifteen. He put Himself through college in New Mexico and finally Being An engineer at Exxon. Jeff attended Miami Palmetto High School and is a class Valedictorian. He went to Princeton and designing for a review study physics. He believe, however, that the other students that physics is
arms back, increasing the tension. A spear or rock was loaded onto the ballista, and the release pin was pulled. The tension on the arms pulled them forward, and the spear or rock was propelled forward by the rope in between the arms. Ballista Physics The design of the ballista is such that the force applied from the projectile comes from the tension of the twisted ropes. The ropes, when the tension is released, tend to return to their rest state with minimum tension, much like a spring
DP Physics IA Thermal physics: Specific Heat Capacity of Metals Introduction: In this experiment we are going to measure the specific heat capacity of a unknown metal. To measure the specific heat capacity we will heat up the metal to certain temperature and release the metal in beaker filled with water. By knowing the mass and temperature of water filled in beaker, we will be able to calculate the specific capacity of unknown metal by change in temperature of beaker willed
football or swimming in a pool, the idea of the forces behind motion feeds my imagination. I aim to become a mechanical engineer someday. Considering this fascination, I was fortunate to be able to learn about motion and forces in physics class. Given the opportunity to research an IA of my own interest, I wanted to learn more about forces. Naturally, I narrowed down this topic to include one of the most influential moving mechanical systems in the modern world…an automobile. However, as it would be potentially
a deeper and better understanding of area is gained as they are provides with different perspectives and different methods to understand. In natural sciences while performing a physics experiment there are multiple ways of knowing used like sense perception, emotion and imagination. Example while performing my physics IA though the readings were taken with the technology but my sense perception/vision also helped me to observe the experiment and to make qualitative data. While writing the lab report
life. I explored the chi square test from the probability unit and its influences in the field of biology. Prior to my research I had a narrow perspective that mathematics was mainly used in the fields of engineering and physics. However, my thoughts were disproven as I explored my IA. The chi square test is used to predict biological hybrids and the null hypothesis of a certain hybrid occurring. From this research process, I learned the importance how mathematics is even in subjects that don’t seem
