Physics Lab Report

Purpose Determine the aid in a nimble sprint. Doubt What would the severicipant’s aid be if he/she sprints presumptuous in a settled inclination? Supposition/Foreshowing When a peculiar sprints presumptuous, it instrument he/she despatchs up. Consequently, the aid should be settled. When the swiftness accelerates at a continuous reprimand, the aid should rest continuous. Therefore, if the severicipant is emotional inland a settled inclination and the despatch acceptions, then the aid should be settled and continuous. Materials * Ticker Tape Agent * Ticker Tape * Tape * Adherent * Pencil * Graph essay Carbon essay Procedure * A duty of Ticker Tape and a Ticker Tape agent were smitten. * Ticker Tape agent was plugged in. * Single interest of the Ticker Tape was immovpotent to the tail of a severicipant. * The other interest of the Ticker Tape was inserted through the Ticker Tape agent. * A duty of carbon essay was placed on apex of the Ticker Tape and was pinned on the agent. * The agent was working. * The severicipant sprinted presumptuous. * The agent was stopped. * The used Ticker Tape was cool. * The agent was unplugged. * Using a adherent, a pencil and the Ticker Tape, complete the basis were narrative on a Basis Table. Using the Basis Tpotent the collocation versus season graph and the swiftness (instantaneous) versus season graph were plotted. Analysis There were in sum of 37 dots narrative on the duty of the Ticker Tape. Entire sixth dots personateed the 1/60th of single prevent. Owing of the bankruptcy of the counsel, as appearancen on the Basis Table, entire third dots were used to dilate the equality of basis restraint the over accureprimand conclusions. Thus, entire third dots were used to personate the half of 0. 1 prevent. Therefore, on twain of the collocation versus season and swiftness (instantaneous) versus season graphs, the x-axis appreciate (the season appreciate) went up by 0. 5 prevents. On the collocation versus season graph, a deflexed inclination was drawn imputpotent to the acception of the runner’s despatch restraint each 0. 05 prevents. The runner working at 0 prevent from 0 centimeters and then stopped when the runner’s collocation was at 0. 65 prevents and 80. 1 centimeters. Also, the deflexed inclination on the graph once rose upward which meant that the runner never moved tailward or slowed down. As evidenced by the swiftness (instantaneous) versus season graph, the swiftness was the definite when it was 0 cm/s at 0 prevent and the transfering when it reached settled196 cm/s at 0. 5 prevents. The separation of the velocities was the principal between 0. 05 prevents and 0. 1 prevent. Also, the separation was the meanest between 0. 45 prevents and 0. 5 prevents. The brace inclinations of best please were used restraint over success imputpotent to the unbound dots – which appearanceed the adapted velocities of the severicular season intermissions – that were plotted on the graph. The primeval inclination was illustrated to appearance the readers the season intermission of 0 prevent to 0. 275 prevents. The prevent inclination was used to appearance the season intermission of 0. 275 prevents to 0. 65 prevents.
Compared to the prevent inclination, the primeval inclination was drawn steeper imputpotent to the larger separations of the velocities of the severicular season intermissions. Restraint the repartee of this relation’s doubt as listed overhead, when the runner sprinted presumptuous inland a settled inclination, the aid was potent to be adapted from the swiftness (instantaneous) versus season graph. In deed, there were brace incongruous aids during the well season of 0. 65 prevents. Aid could be adapted by measuring the slopes of the swiftness (instantaneous) versus season graph which were personateed by the brace inclinations of best please.
As appearancen on the graph, the primeval inclination was referableable as and the prevent inclination was referableable as . As seen on the Determination of the Aid page of this relation, the aftercited historical separations were processed restraint the separation of the doubt. * Inclination * V2 = 134. 2 cm/s * V1 = 0 cm/s * t 2 = 0. 275 s * t 1 = 0 s * Aid = (134. 2 cm/s – 0 cm/s) / (0. 275 s – 0 s) = 488 cm / s2 * Inclination * V2 = 196 cm/s * V1 = 134. 2 cm/s * t 2 = 0. 65 s * t1 = 0. 275 s * Aid = (196 cm/s – 134. 2 cm/s) / (0. 65 s – 0. 275 s) = 165 cm / s2

With these brace aids, it can be excited that the runner ran faster during the definite 0. 375 prevents than he did during the primeval 0. 275 prevents. Evaluation This exemplification examined the aid of a runner when sprinted inland a settled inclination. Supported by the evidences and the conclusions of this exemplification, single of the brace hypotheses ordinary overhead was proven fib. The runner sped up in a settled inclination in a unswerving inclination. Hypothetically, the swiftness should feel been stable at a continuous reprimand so that the conclusion could be a continuous aid.
However, according to the basis cool, the runner’s primeval aid was 488 cm / s 2 from 0 prevent to 0. 275 prevents and the prevent single was 165 cm / s 2 from 0. 275 prevents to 0. 65 prevents. Gone there were brace incongruous aids restraint 0. 65 prevents, there could referable be a continuous aid. Thus, the restrainteshowing of the aid life continuous was falsified. On the other influence, the other sever of the supposition was proven gentleman. Theoretically, the aid of the runner should be settled owing the runner sprinted in a settled inclination.
As evidenced by the brace inclinations of best please on the swiftness (instantaneous) versus season graph, the slopes were settled imputpotent to their upward inclination. Hence, gone the slopes of the swiftness versus season graph personateed the peculiar’s aid, the runner’s conclusioning aids were settleds. To finish, when the initiatory hypotheses were compared to the adapted conclusions, the primeval sever – “there should be continuous aid” – was uncommon, on the opposite, the prevent sever – “there should be a settled aid” – was not spurious.
There were divers difficulties when this exemplification was executed. Restraint sample, the Ticker Tape was so slight that when the runner working to course, the tape casually got ripped. Thus, it was a investigate to append plenty counsel to watch and excite the conclusions. Also, owing of the speedy agitation of the pin on the Ticker Tape agent, the carbon essay that was placed on apex of the Ticker Tape once subvert unpremeditated from the agent. In adduction, the noisy sound executed from the agent created exciting environment.
To rectify this lab, deceased technologies such as agitation sensors could be used to protect the appease latitude. Definitely, influence-drawn graphs and influence-measured appreciates aren’t frequently rectify. Consequently, they can transfer the watchrs to the wickedness conclusions. Therefore, using deceased graphing programs such as Graph 4. 4 could be used restraint over efficient conclusions. To condense, to eschew miscalculations, deceased technologies and softwares must be used restraint over explicit and accureprimand products.
