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

are parts of physics study. 1) When we walk or run‚ our motion is part of laws of mechanics and thrmodynamics. 2) We eat food which undergoes chemical reactions producing heat energy which is converted into mechanical energy 3) Use of refrigerator‚ pressure cookers‚ washing machines‚ television‚ music system‚ computers‚ etc. are all designed on the principles of physics. 4) When we speak‚ we produce sound properties of which like pitch and intensity are studied in physics 5) Electricity

Purpose/ Hypothesis: The purpose of the lab is to explore some of the variables that influence projectile motion using a Rubber Band Cannon and launching rubber bands and measuring its horizontal distance and angle at which the rubber bands has been launched.. Materials: Materials used for the lab were a Cardboard Box‚ a 30cm ruler‚ rubber bands‚ a measuring tape‚ tape‚ a pencil‚ a paper protractor cut out‚ and scissors. Procedure: For the lab‚ scissors were used to cut the paper protractor cutout

Brownian motion This is‚ presumably the random drifting of particles suspended in a fluid (a liquid or a gas) .This movement was discovered and later named after botanist Robert Brown (1773-1858). He was a Scottish botanist and palaeobotanist who made important contributions (including Brownian motion) to botany largely through his pioneering use of the microscope. The scientist who made Brownian motion famous is Albert Einstein‚ who brought the phenomenon to the attention of the larger physics community

Make a pendulum clock whose pendulum has a period of two seconds. Calculations shows that the length of a pendulum if this period with a fixed support would be about one meter. Make a pendulum with a yielding support. ix) Use the results from the experiment to calculate a value for d that would give a period of two seconds for the pendulum used. x) Use your answer to (ix) to suggest whether the use of a yielding support would save space.

I started vacuuming‚ that took me at least 2 hours because I ended up vacuuming the entire house. I was sooo tired when I finished‚ I had 6 hours left before Jennifer Lawrence arrived‚ what should I do to impress her? I mean besides talking about physics? I decided I’d make some coffee for the two of us‚ while all of this happens I remember that the A/C turns on every 30 minutes for 30 minutes‚ so it is on for 12 hours a day‚ then I remember to wash my dishes‚ so I put them in the dishwasher‚ which

The following is a project made by anonymous: INTRODUCTION The general purpose photoconductive cell is also known as LDR – light dependent resistor. It is a type of semiconductor and its conductivity changes with proportional change in the intensity of light. There are two common types of materials used to manufacture the photoconductive cells. They are Cadmium Sulphide (CdS) and Cadmium Selenide (CdSe). Extrinsic devices have impurities added‚ which have a ground state energy closer to the conduction

The Ballistic Pendulum Crime Lab Physics You are a criminologist‚ and have been given a gun which has been used in the commission of a crime. Both prosecution and defense claim that "muzzle velocity" (speed of the bullet as it leaves the gun) is crucial to the case. Your job...FIND IT! Shown below is a diagram representing a "ballistic pendulum." The bullet is fired into the block‚ the bullet-block combination rises by a height h as shown‚ a little physics is applied‚ and ...voila!...there
