Checking Newton Essay Example for Free

Checking Newton EssayIn this experiment I will thread measurements on a two pulley system and use them to check Newtons 2nd lawThe localize of momentum of a bodyIs directly proportional to the external,Resultant force acting upon it. The change in momentum takes place in theDirection of that force. The apparatus is set up as shown in the plot belowThe masses m1 and m2 are initially set at 400 grams each. The ruler is set vertically. I measured and recorded the distance (S). on that point must be the same friction at the pulleys in order to comply with this took added 10 grams masses to m1 until the two masses jus begin to move. I recorded the superfluous masses m0 added, and the total mass M of m1 and m2. I then held m1 by hand, added one 10g mass, and released it. My partner at that exact moment started the stopwatch. When the m1 hit the soft material the stopwatch was stopped. I recorded the time interpreted in the table below and repeated this a further one more time so I could finally take an average reading.Extra mass added to m1 condemnation 1 s Time 2 s Mean Time Timei 1/(m Kgs-1 0. 020 3. 0 4. 18 3. 59 12. 8 50 0. 040 1. 60 2. 14 1. 87 3. 49 25 0. 060 1. 62 1. 45 1. 53 2. 34 16. 6 0. 080 1. 19 1. 30 1. 24 1. 53 12. 5 0. 100 1. 19 1. 0 1. 09 1. 18 10 On then ext page is the graph that I plotted with t on t on the y- axis against 1/(m on the x- axis.Theory The string is assumed inextensible so then the emphasis is the same at all points. For the downward motion of the mass m2 I applied F=ma.M1g T = m1a 1 For the upward motion of m2 T m1g = m1a 2 Adding 1 and 2 cancels out T M2g m1g = m2a+m1a (m2 m1)g = (m2+m1) a There for a = m2-m1/m2+m1 g 3 Now s=ut + at U=0, and There for s=1/2at A=2s/ti 4 Substituting 4 in 3 for a 2s/t = (m/M g ( 2Ms= t. g. (m This can be written asti = 2Ms/g . 1/(mm, s and g are constants. So a graph of ti against 1/(m should result in a bully line through the origin.
