Physics 12 - Circular Motion Extra Problems 1. A 1400 kg car is travelling at 25 m/s on a circular hill of radius 210 m. What is the normal force on this car at the top of the hill? [pic] [pic] 2. In an amusement park‚ a 2.8 m radius “drum” rotates such that a person does not fall when the “floor” drops away. [pic] If the coefficient of friction between the person and the wall is 0.35‚ what is the maximum period of the rotation so that a person will not fall? A. 2.0 s B. 3.4 s C.

Year 11 Preliminary Physics Assessment Tasks Year 11 Preliminary Physics Assessment Tasks Research Report – Models of the Universe Research Report – Models of the Universe Date Due: Friday 31st Agust Weighting: 15% Abstract The Universe is where everything exists‚ matter and energy. There are two main models of the universe: the geocentric model and the heliocentric model. The geocentric model is where the Sun and other planets‚ moons and stars revolve around the Earth. The

In the Tumble Buggy Lab‚ my partners and I used several different methods to calculate the velocity of a Tumble Buggy. The methods we used were a meter stick and a timer‚ a Spark Timer‚ a Photogate‚ and a Motion Sensor. Each method was different but overall‚ our velocities were very similar. Using the meter stick and timer‚ our velocity was 0.22 m/s. With the spark timer‚ our velocity was 0.26 m/s. Next‚ the velocity found with the Photogate was 0.325 m/s. Finally‚ when we used the motion sensor

Experiment 7: Relative Density Laboratory Report Marella Dela Cruz‚ Janrho Dellosa‚ Arran Enriquez‚ Alyssa Estrella‚ Zacharie Fuentes Department of Math and Physics College of Science‚ University of Santo Tomas España‚ Manila Philippines Abstract The experiment was conducted to show the different methods on how to determine an object’s composition through its density and to determine an object’s density by displacement method and the Archimedes Principle. Results show that. The materials

My lab results were similar to my hypothesis. My hypothesis was that the densest object would be the rubber stopper. In the lab results the densest object was the penny and the rubber stopper was second. My hypothesis was switched. My hypothesis was correct when I stated that the macaroni was the third densest object. My hypothesis was also correct for the dice‚ but the bead and the dice share the same density. So they are both the fourth densest item. I was wrong with my hypothesis when I placed

Abstract :The purpose of the experiment is to explore elastic and inelastic collisions in order to study the conservation of momentum and energy. The guided track‚ carts‚ photogates ‚ 250 g weight and picket fences were the primary components used in the procedural part of the experiment. Each experiment involved the use of the photogates and picket fences to measure the initial and final velocities of both carts when they collide. The data was collected and translated to a graphical model for further

LAB # 5 Relationship Between Drop Height and Diameter of Plasticine Sphere PROBLEM: A student suggest that there is a proportional relationship between height at which a plasticine sphere is dropped and the diameter of the flattened part after dropping. Design an experiment to determine if this suggestion is true or not. AIM: To investigate the relationship between the drop height and the flattened part of a plasticine sphere after being dropped. HYPOTHESIS: As the height of the sphere plasticine

second smallest planet in the solar system. It is 4‚879 kilometers across. Compare that with our moon‚ which is 3456 km across‚ and you can see that mercury is not very big. In fact‚ Jupiter’s moons Ganymede and Callisto and Saturn’s moon Titan are bigger! Even though those moons are bigger‚ Mercury weighs a lot more than they do because it is made of mostly metal and rock. In fact‚ Mercury has the most metals for its size of any planet in the solar system. Mercury is also the closest planet to the sun

Molecular Modeling Exercise The purpose of the is lab was to practice modeling molecules and exploring the capabilities of the ChemOffice programs. The minimum energy was found for each of the three molecules tested and the strain energy at different dihedral angles was plotted. The first molecule‚ butane‚ was easily completed but amphetamine and U4EA caused some difficulty. The results of the last two were not very conclusive. INTRODUCTION The purpose of this lab was to explore the capabilities
