    Graphical Analysis of Motion Introduction To graphically analyze motion‚ two graphs are commonly used: Displacement vs. Time and Velocity vs. Time. These two graphs provide significant information about motion including distance/displacement‚ speed/velocity‚ and acceleration. The displacement and acceleration of a moving body can be obtained from its Velocity vs. Time graph by respectively finding the area and the slope of the graph. Data Tables – Part I Displacement (m) Time (s) 0.10 m

    moving has momentum. Momentum is equal to the objects mass times its velocity. Momentum is conserved‚ which means that “momentum before an event equals momentum immediately after‚ or pi=pf”. Since pi=pf‚ then pai+ pbi = paf+ pbf and (ma* vai)+ (mb* vbi)= (ma* vaf) + (mb * vbf). Having velocity simply means that an object has a speed and direction. Using the formula “(ma * vai) + (mb * vbi) = (ma* vaf) + (mb * vbf‚)” the final velocity of two carts after they collide can be found. The first cart is

    introductory height of two meters would be far too great causing the egg to break. Therefore‚ lab participants needed to find a way to either elongate the duration of the impact‚ or find a way to slow down the egg’s normal final velocity when it strikes the ground. Velocity is described as‚ “the displacement divided by the time interval during which the displacement occurred” (Serway & Faughn‚ 2002‚ p. 43). Prior to the trials at the set heights‚ there seemed to be multiple structural designs

    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 the

    collisions. This background knowledge is essential in understanding the experiment‚ resulting calculations‚ and analysis. The main objective of this experiment was to determine the initial velocity of a ball shot from a spring loaded gun‚ into a receptacle which traveled up a ramp. As well as finding the initial velocity of the ball we also wanted to determine the spring constant of the spring used in the spring loaded gun. Lastly‚ we wanted to analyze what speed would theoretically be reached if no

    high speed and covers a relatively large distance in a short amount of time. * Velocity: Velocity is a vector quantity that refers to "the rate at which an object changes its position."  When evaluating the velocity of an object‚ one must keep track of direction. It would not be enough to say that an object has a velocity of 55 mi/hr. One must include direction information in order to fully describe the velocity of the object. * Distance: Distance is a scalar quantity that refers to "how
