The object of this lab was to study the conservation of nervous impulse and deviate in
kinetic cypher in one-dimensional collisions where in an rubbery collision, both momentum and kinetic energy are hold as opposed to in rubbery collisions in which only momentum but not kinetic energy is conserved.
Theory
In elastic collisions kinetic energy K should be Kf / Ki -1 =0 and momentum P Pf/Pi = 1, whereas Pf/Pi = 1 but since Kf?Ki, ?Q/Ki ?0 in inelastic collisions.
The velocities for the pull understructure be found by using the following description of velocity:
v= distance
time
Kinetic energy is the energy associated with an objects state of motion. It is defined as maneuver needed to accelerate the object from rest to current velocity.
K = ½mv2 (joules)
Where m=mass of cart and v2 = velocity of the cart.
Standard variance of the mean:
?m = ?i=1n (xi-xm)2
n(n-1)
Where xi= calculated abide by
Xm= value of the mean
n= total amount of repetitions of measurements
Percent difference:
%= |mean- GAV| x 100%
GAV
Where GAV= general accepted value
Average: Xm= ?in = xi
n
Where x= individual measurements
n= total amount of repetitions of measurements
Experimental procedure
frontmost the air track was leveled and then the two photogate units were placed virtually 100 cm from each other. After hooking up the photogates to the digital channels of the 750 interface, both carts, one heavier than the other, were weighed on a triple- convey balance and the length of the tab on top of the cart was measured. The photogates were set up in a height so that only the tab would pass through the light beam of the gates in order to calculate the velocity of the cart. In the first part of the experiment, the heavier cart was set stationary in the middle of the lightbeams on the airtrack and the lighter cart was send towards it so that both metal ends of the carts would...If you want to get a spacious essay, order it on our website: Orderessay
