The Hubble telescope is a telescope that takes pictures of the universe and has transformed the way scientists look at our universe. The Hubble telescope circles the Earth in 97 minutes at a speed of about 5 miles per second. The telescope has taken hundreds of thousands of fascinating pictures of our universe and all the amazing parts of it. The Hubble telescope was named after Edwin Hubble who had made some of the most important discoveries in astronomy. Hubble travels more then 150 million

Cart on a Ramp Argument Essay The experiment can be used to determine the acceleration due to gravity accurately when the slope of the ramp is extrapolated to 90 degrees. Experimentally‚ the acceleration due to gravity is valid because when the ramp is set to a 90 degree angle‚ it essentially has no slope‚ so objects that are set at a 90 degree angle experience free-fall which is 9.8 m/s2. Using this knowledge‚ during the experiment if the ramp is set at a higher slope‚ it is essentially approaching

Johnny von Neumann “There are two kinds of people in the world: Johnny von Neumann and the rest of us.” Eugene Wigner‚ Nobel Prize winning physicist. December 28‚ 1903 a mind unlike any other was born‚ Janos Neumann. Janos Neumann was the first born son of Max Neumann‚ a non-practicing Hungarian Jew. Max Neumann had very good education‚ he became a doctor of laws and later worked as a lawyer for a bank. Early in Janos ’ life‚ Max bought a title which he never used but his son‚ Janos did. The

Introduction “The more you find out about the world‚ the more opportunities there is to laugh at it” said Bill Nye the person who changed the way kids look at science. Kids would never known so much about science if “Bill Nye the science guy” hadn’t been around. Because of Bill kids enjoy the fundamentals of science and want to learn more. Bill Nye found the key to teaching science to kids is to be funny. Bill Nye also is a comedian and a mechanical engineer which he also has influenced the world

Assignments in Science Class IX (Term I) 10a Gravitation IMPORTANTIMPORTANT NOTES NOTES IMPORTANT NOTES 7. Acceleration due to gravity of the Earth : The acceleration with which the bodies fall towards the earth is called acceleration due to gravity. Its average value is 9.81 ms–2. 8. Variation of acceleration due to gravity. (i) Acceleration due to gravity changes with the change in distance from the centre of the earth. (ii) Acceleration due to gravity is maximum at the poles of the earth

Abstract: The previous lab explored the effect of gravity on free fall. It was determined that acceleration is always constant under free fall. However‚ in this lab‚ acceleration was observed under different forces‚ other than just gravity. Therefore‚ depending on how strong the forces being exerted were‚ acceleration differed. It wasn’t constant anymore. Using a glider on a air track and a pulley‚ different masses were attached at the end of the string and the glider was allowed to move on the

The trebuchet is made of five basic parts. The base‚ counterweight‚ throwing arm‚ sling‚ and pivot. The base gives the trebuchet a secure base to help with over rotation and other engineering problems that may occur. The counterweight falls and the force of gravity thrusts the projectile forwards. The throwing arm is used to connect the counterweight and sling‚ and is part of the thrust downwards.The sling holds the projectile and the pivot is there to prevent over-rotation. Trebuchets can be made

7 Day Creation “You will never find time for anything. If you want time‚ you must make it‚” an aphorism that has been a great influence in my life. I mean‚ what is time? Time is a non-spatial continuum in which events occur in apparently irreversible succession from the past through the present to the future. To me‚ time is just a pigment of one’s imagination‚ and that travelling back and forward through it is all a matter of splitting the space-time continuum‚ and creating a portal or vortex

Multiple Choice Question 6.31 A 1000-kg car moving at 10 m/s brakes to a stop in 5 s. The average braking force is 3000 N 5000 N 2000 N ***(answer) 1000 N 4000 N Force = mass x acceleration. Acceleration = velocity/time = -10/5 = -2 m/s/s. (- sign means a deceleration from velocity of 10 to 0) Force = 1000 x -2 = -2000 Newtons (i.e. 2000N in opposite direction to motion) Multiple Choice Question 6.11 When you jump from an elevated position you usually bend your knees upon reaching

Creation Vs. Evolution Name: Sara Ana Reed Grade: MYP2 Subject: Biology Task: Writen Essay - * There is a question that I ask myself very often‚ it is a question that doesnt have an answer. How was the world created? There are different theories on that theme‚ but here are 2 man theories in which we believe in‚ the Big Bang theory (scientific theory) and the Creation theory (religious theory). We cannot say that one theory is right and one is wrong because they both have evidence to
