AP Physics HW #1 Multiple Choice 1. A car travels 30 miles at an average speed of 60 miles per hour and then 30 miles at an average speed of 30 miles per hour. The average speed the car over the 60 miles is (A) 35 m.p.h. (B) 40 m.p.h. (C) 45 m.p.h. (D) 10 m.p.h. (E) 53 m.p.h. Answer: B. Method: Vavg = Δx/Δt The average speed is the total distance traveled‚ divided by the total time. They give us all distances traveled is‚ so we just need to find the time. We find the time‚ by applying

Good morning/ afternoon everyone First of all‚ thank you for inviting me to this exhibition of Poetry in Motion. I was inspired to create my work based on the poem called This Man‚ by the Solomon Islands poet‚ Celo Kulagoe. This poem is a critique of the all-encompassing power of money‚ which can dictate to presidents and prime ministers alike and can ruin those with few resources. This resonates with the current issue of Coal Seam Gas mining and its wealthy supporters‚ while the dangers to the

Clocky ClockyClocky is a brand of alarm clock outfitted with wheels‚ allowing it to hide itself in order to force the owner awake in an attempt to find it. Invented for an industrial design class by Gauri Nanda‚ then a graduate student at MIT Media Lab‚ Clocky won the 2005 Ig Nobel Prize in Economics.[1][2] After earning her Masters Degree from MIT‚ Nanda founded a company‚ Nanda Home‚ to commercialize Clocky and other home products. History The original prototype‚ built in three days‚ was

Motion in a Viscous Medium Aim The aim of this experiment is to measure the terminal velocity of spherical beads falling under gravity in a liquid determine‚ and hence determine its viscosity using Stoke’s law. Introduction When a stationary solid object is complete or partially immersed in a fluid‚ it experiences an upthrust or buoyant force. According to Archimedes’ principle‚ this buoyant force B is given by where ρ is the density of the fluid‚ Vs is the immersed volume of the

Uniform Circular Motion PES 115 Report Objective The purpose of this experiment is to determine the relationships between radiuses‚ mass‚ velocity and centripetal force of a spinning body. We used logger pro to accurately measure the orbital period of the spinning mass and used these measurements to determine the interrelated interactions of the specified properties and viewed the results graphically. Data and Calculations The black markings on the string are about 10 cm apart in length‚ measured

6 R’s The 6 R’s are an important checklist. They are used by designers to reduce the environmental impact of products. They can also be used to evaluate the environmental impact of other products. Respect – In order to understand what it means to be a part of the solution‚ you have to begin with respect. Respect for all things: people‚ animals‚ bugs‚ birds‚ fish‚ snakes‚ rivers‚ lakes‚ oceans‚ trees‚ mountains‚ valleys and so on. Rethink — Everything on Earth is connected‚ and every decision

Lab II: Description of Motion in Two Dimensions‚ Problem III: Projectile Motion and Velocity John Greavu February 13‚ 2013 Physics 1301W‚ Professor: Evan Frodermann‚ TA: Mark Pepin Introduction "A toy company has hired you to produce an instructional videotape for would-be jugglers. To plan the videotape‚ you decide to separately determine how the horizontal and vertical components of a ball’s velocity change as it flies through the air. To catch the ball‚ a juggler must be able to predict its position
