Describe, in detail, a procedure to test your hypothesis. Identify the controlled variables. First I would make to paper airplanes but of the same paper. One would have a longer wing span and one would have a shorter wing span. Then I would go to a room that had no wind and I would throw each paper airplane 3 times to get accurate results then I would combine them to get my result on witch plane flew the farthest.
An astronomer who wants to send a rocket into space uses calculus to work out how much fuel the rocket needs to accelerate to the correct velocity. These are just some examples of the ways in which calculus and astronomy work together. How to Bring Your Rocket Up to Speed Space travel is extremely important to astronomy. Space-based telescopes and probes, which collect huge amounts of information about the Solar System and beyond, are launched into space using powerful rockets. The rockets accelerate the spacecraft until it is going fast enough to leave the Earth's gravitational pull and set off on its journey.
Physics Lab Report: Popper Hopper. Purpose: The purpose was to find the speed of a hopper popper as it leaves the table. Materials: The materials used were a timer, ruler and a popper Procedure: I put the popper on the table. When it popped up in the air i looked how high it went up and how long it took. Data: |Trial # | | |4.5 secs |52 cm | |3.1 secs |90 cm | |2.8 secs |84 cm | |1.3 secs |74 cm | |.8 secs |65 cm | Calculations & Data Analysis: Given: mass = .0102 kg, height = .73 m, g= 9.8 m/s Unknown: velocity?
9. Find the average time for each clay with different mass to hit the ground. 10.Find the speed of the parachute in each trial and the random uncertainty from the repeat trials. 11.Plot a graph of mass (x-‐axis) against time (y-‐axis) to look for a relationship. If the first graph is not linear it will be necessary to further process the data and plot further graphs to try to find a
Evidence proving that flight MH-17 was taken down by a BUK missile. This fragment shows part of a serial number with a broken 2 and a Cyrillic Ц from the Russian alphabet. Interestingly proof flight MH-17 was brought around a rocket. This is demonstrated by a scientific examination concerning ammunition sections from flotsam and jetsam of the plane, requested by RTL News. Global specialists underwrite the finish of this examination, MH-17 has been brought around a BUK rocket.
Try collisions in which the initial velocity of glider2 is not zero. You may need to practice a bit to coordinate the gliders so the collision takes place completely between the photogates. Data and Calculations For each time that you measured, calculate the corresponding glider velocity (e.g., v1, = L1/t1i). Use your measured values to calculate Eki and Ekf, the combined kinetic energy of the gliders before and after the collision. Record your results in the table.
Lab 1: Introduction to Scientific Inquiry Purpose: To show how the processes of scientific inquiry can help you learn about the natural world. Materials: * Pencil * Physical Science Lab Record Sheets * Virtual Physical Science CD-ROM * Computer * Microsoft excel * Microsoft word Introduction: 1. Posing Questions: Have you ever observed how a gas in a balloon acts when heated? What did you see? What questions could you ask about how changing temperatures affects the gas in a balloon?
Although rocket pioneer R.H. Goddard and the Peenemunde rocket scientists used inertial sensors for navigation and control of missiles, a complete navigation system using inertial sensors did not emerge until the 1940s under Charles Stark Draper, considered to be “the father of inertial navigation.” C.S. Draper established the Instrumentation Laboratory at MIT as a major player in the early development of inertial navigation. In the 1960s, engineers at MIT designed the inertial navigation system (INS) for sensing and controlling rocket thrusting during trajectory changes of the Apollo spacecraft [12]. The dominant inertial sensor errors for the Moon missions were unpredictable shifts in output biases of the gyroscopes and accelerometers. These
Abstract - In this experimental study, the mixing characteristics of six different symmetrical twinjet configurations like circle-circle, hexagon-hexagon, ellipse-ellipse, square-square, triangle-triangle and star-star were determined. Both the nozzles in the twinjet are convergent with circular inlet which varies smoothly to different geometrical exit. The nozzle spacing S between the two nozzles is 20 mm and nozzle spacing to nozzle exit diameter ratio (S/D) was maintained constant as 2. The centerline Mach number decay in axial direction and Mach number decay in radial direction were measured and plotted. Measurements in axial direction were carried out for different Mach numbers such as 0.4, 0.6 and 1.
The movement of a pure solvent to equalize solute concentrations on each side of a membrane generates osmotic pressure. Applying an external pressure to reverse the natural flow of pure solvent, thus, is reverse osmosis. History of Reverse Osmosis First Demonstration of Reverse Osmosis Professor Sidney Loeb and engineer Ed Selover remove newly manufactured reverse osmosis membrane from plate-and-frame production unit circa 1960. In the late 1940s, researchers began examining ways in which pure water could be extracted from salty water. During the Kennedy administration, saline water conversion was a high priority technology goal-"go to the moon and make the desert bloom" was the slogan.
