The document provides instructions for 8 tasks to complete related to Isaac Newton and his laws of motion. The tasks direct the student to various websites to find information about Newton's life, contributions to science, his 3 laws of motion, and examples of each law. The final task involves calculating the time it would take a car to stop if the engine suddenly stopped while traveling at a given speed, taking into account various friction forces.

1. IES Auringis. Jaén. José Cayetano Bautista Expósito 4º ESO. Physics and Chemistry. Unit 4 Read the directions for each task, then go to each website and find the information. Write the answers on a paper with your name on it. Task 1 : Who was Isaac Newton? What important contributions did he make to science? http://www.windows.ucar.edu/tour/link=/people/enlightenment/newton.html Task 2: What was Isaac Newton's childhood like? http://www.pbs.org/wnet/hawking/cosmostar/html/cstars_newt.html Task 3: Look at a picture of Isaac Newton. Write 1 or 2 sentences that describe what he looks like. http://www.google.com Task 4: What is Newton's 1st law? Describe the example of Newton's 1st Law from the webpage. Has this ever happened to you? What did Newton call his first law? http://www.schools.utah.gov/curr/science/sciber00/8th/forces/sciber/newtons.htm Task 5: Newton's 2nd law is F = MA. Write the formula in words. Why does a speeding bullet and a moving train have so much force? http://www.schools.utah.gov/curr/science/sciber00/8th/forces/sciber/newton2.htm Task 6: What is Newton's 3rd law? What example was described on this webpage? http://www.schools.utah.gov/curr/science/sciber00/8th/forces/sciber/newton3.htm Task 7 : What is friction? What are the three types of friction? http://www.schools.utah.gov/curr/science/sciber00/8th/forces/sciber/forcmot.htm Task 8: Which velocity will reach a car, with a weight of 950 Kg, that goes at 55 km/h if the engine force of 2500 N pushes it forward during 2 minutes and there is a fluid friction force caused by air of 100 N and a rolling friction force of 250 N caused by the wheels? If the engine stops suddenly at that speed, and we consider that the friction forces remain with the same values, how long does the car take to stop?
