In order to investigate the phenomenon, the density of the hanging object is going to change, and by recording the time it takes the object to complete a period hanging from the pendulum. According to pendulum’s theory, the period should be the same because the†¦show more content†¦The time is proportional to the density at a gradient of 0.7798 seconds per gram over a milliliter. Although the points should be in a straight line, I can infer that there is a little deviation because of a systematic error, due to the observer. This time the systematic error didn’t make a big difference when sketching the graph. When thinking of speed, the more speed an object has means the more distance it is going to travel, this should justify my results because as the object gets denser the mass is greater therefore the it will gain more speed as soon as its droppe d so it would travel more distance making the period longer than the less dense ones. Evaluation and Improvements: Weaknesses | Improvements | One weakness I faced was the accuracy of the measurements while taking the time, when recording the time I hold with one hand the object being dropped and with the other one start the stopwatch. Therefore, while trying to hit the start button I could have probably slightly changed the release point or vice versa. Although my measurements could have been more accurate the limitation didn’t affect that much my data. | I can improve my weakness by instead of me holding both things I could put a camera on front ofShow MoreRelatedIb Physics Ia2482 Words   |  10 PagesIB 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 internalRead MoreIb Physics Ia - Domino Effect1271 Words   |  6 PagesChee 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 completelyRead MoreIb Physics Ia-Freefall Essay749 Words   |  3 PagesAIM 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 alwaysRead MorePhysics : Calculus Ia Section 2771 Words   |  4 PagesCalculus 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 ≠¤ 2Ï€. (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 ¬Ã‚ ¬Ã‚ ¬-t (cos t – sin t); x’ (t) = 0 when cos t = sin t. Therefore, x’ (t) = 0 on 0 ≠¤ t ≠¤ 2 Ï€ for t = Ï€/4 and t = 5 Ï€/4. For the absolute minimum are at t = 0, Ï€/4, 5 Ï€/4 and 2 Ï€. The particle is farthest to the left when t = 5 Ï€/4.

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 springRead MoreThermal Physics Ib Dp Lab1045 Words   |  5 PagesDP 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.
