    Velocity The word‚ velocity‚ originates from the Latin word‚ vēlōcitās‚ meaning swiftness or speed. Velocity is one of the basic words used in mathematics and physics and forms the basis for the more important formulae used in high level study of these subjects. According to the dictionary‚ the definition of velocity is the rate of change of position of an object. In simple words‚ velocity means the distance travelled by an object over some time divided by the time taken by the object to travel

    Ben Snyder Constant Velocity Lab To the Left: The Position Vs. Time graph Red: Run #1 Blue: Run #2 Green: Run #3 Purpose: To find what the slope of a position vs. time graph represents. Q.1) The Slope of the second run is greater than the slope of the first run. The first piece of evidence is in the data calculations themselves. In run number 1 the calculated slope 15 m/s which is considerably less than the slope of the second run which was at a swift 0.27 m/s. Also as you can clearly see

    Laboratory – Terminal Velocity Introduction: Consider dropping a piece paper and a brick from the same height. Although in theory they should both strike the ground at the same time; in practice the brick will always strike the ground first. The reason is because of air resistance. As the paper falls to the ground air resistance is pushing the paper up‚ this slows the acceleration of the paper. It is known that as the velocity of an object increases the air resistance acting on the object

    as plotting of the data on the graph. The velocity versus time graph came out to be a quadratic model‚ having a number of curves. Since this is based off of original measurements‚ any mistakes in measuring would have been multiplied when the velocity was calculated‚ so human error could be prevalent here as well. Conclusion Our hypothesis was only partially supported. The position versus time graph was a linear model‚ as predicted‚ but the velocity versus time graph was quadratic‚ not supporting

    initial height. A motion detector is mounted on the ceiling directly above the ball‚ facing down. So‚ the positive direction -- the away-from-the-detector direction -- is downward. Draw the position‚ velocity‚ and acceleration graphs. Since moving downward is a positive direction‚ is the velocity positive when the ball falls‚ 0 when it hits the ground‚ and then negative when it moves up? Is the accerlation positive (9.8) as the ball falls‚ very positive when it hits the ground‚ and then neg (almost
