Physics Pendulum Lab

Katherine Unman Introduction/Purpose Pendulums serve a huge purpose that are often overseen by umteen due to technological advancements being made In the everyday world. A simple pendulum consists of a small object (the bob) suspended by a lightweight cord. The mass oft he pendulum is actually only the mass of the bob the mass of the string is not included. The period of a pendulum is the amount of cartridge holder for the bob to complete exactly one cycle or oscillation back and forth.The length of the pendulum extends from the attached end of the string to the center of mass of the bob. The current aim for this investigation was to Investigate the simple pendulum. There are many variables on could look Into, such as displacement, angle, damping, mass of the bob etc. The more or less Interesting variable, however, Is the length of the swinging pendulum. The relations p between the length and the time for one swing (the period) has been researched for many centuries, and has allo wed famous physicists like Isaac Newton and GalileoGalilee to compass an accurate value for the gravitational force acting on it, g. Len this simple investigation, we performed two activities to visually observe what affects the period off pendulum, mass or the length of the string. Hypothesis With our previous knowledge of pendulums and the forces acting on a pendulum, we hypothesized that the length of the string along with gravity would affect the period a ND the mass of the bob would not. Materials In order to complete a successful Investigation, numerous supplies were needed.Without these materials, our observations would not have been as accurate. The mat aerials we used are 1. metre stick 2. Stopwatch 3. Pieces of string, 3 of the same length, and one off different length 4. Washers 5. A partner 6. Pen/pencil Procedure When effectively investigate what affects the period of a pendulum, some simple ye vital steps are necessary to follow. In this experiment, two activities w ere performed t hat share a effectuate of Instructions. These were 1. Gather all the materials
