Project 1: 1. Results for a: ht=500/ spd=0mph —too slow! Satellite crashed into Earth! Results for b: ht=500/ spd=100mph —too slow! Satellite crashed into Earth! Results for c: ht=500/ spd=25000mph —too fast! Satellite left viewing area and took off in space somewhere! I was determined to get a 100%‚ so I played around with the numbers until I found that at 500 miles above the Earth‚ the satellite would have to be launched at 16‚700mph in order to reach a perfect orbit. Below is the explanation

Science Term 1 – Rubber Band Racer – Liam Gist A rubber band racer consists of a corflute base‚ a rear axle with rubber wheels and a front axle with plastic wheels. It is powered by a rubber band that can be wound around the rear axle and when released it propels the racer forwards. When the rubber band is wound around the axle it has elastic potential energy and when this energy is release it is transformed into kinetic energy that rotates the rear axle and wheels propelling the car forwards. As

Scientific Explanations of the World and Agnosticism and Atheism The Big Bang had to occur at exactly the right second. If it didn’t‚ it cannot exist the way it is today. The reason for that is‚ if it happened to soon‚ it would have been too small to form stars‚ and if it happened to late‚ everything would have flown away too quickly to create stars and planets. They believe God caused this to happen. Scientific laws such as gravity made the content of the universe to form how it is today

Einstein’s Point of View When you think of Albert Einstein what do you imagine? A crazy‚ old chemist with white hair that stands straight up? Well‚ Albert Einstein was a chemist with crazy white hair‚ but he also was a chemist who wanted to help America with the use of his knowledge and different point of view. In his letter to President F.D. Roosevelt‚ he uses his knowledge and outside perspective of the subject of uranium to address the problems with the element and ways to improve. In Einstein’s

The relationship between mass and time of oscillation of a slinky Introduction In the 1950’s‚ Richard James accidentally discovered what we called today as the ‘slinky’. As he was trying to engineer a way to keep sensitive ship equipment steady at sea‚ he accidentally knocked some springs off the shelf which caused them to fall. He noticed that these springs appeared to be gracefully “walking” down the shelves instead of them simply falling down. James’ accidental discovery sparked way for further

Name: Lauren Date: February 15‚ 2016 Title: May The Force Be With You Abstract: Experimental Question: How does the mass of the first model source car affect the acceleration of the second model source car at rest to in motion? Research: When we drive our cars‚ motorcycles‚ trucks‚ or any vehicle down the road‚ we are driving them at a certain velocity and direction. All vehicles have a mass to the order of a few hundred pounds. When our vehicles move at a certain speed down the road‚ they create

Any object that fall to the earth have a constant acceleration due to gravity of -9.80 m/s^2 if air resistance is ignored. If an object is small and have a reasonable mass‚ we can predict the final velocity of the object and the time of fall‚ since smaller objects with smaller mass have less air resistance. Objects with smaller masses have less air resistance because their velocities are smaller. Objects with larger masses‚ on the other hand‚ will have more air resistance because their velocities

Objective: Motion on an Incline with Friction The purpose of this experiment is to prove that the experimental acceleration value calculated is close to the theoretical acceleration values by finding the tension force‚ normal force‚ kinetic friction and the coefficient of kinetic force from the data collected. Theory: The forces acted on an object can be divided up into many different components depending on what the object is doing. In this experiment‚ an object is sliding up an incline plane
