We were told to make our own project, i chose to base mine on the conservation of momentum and used the pendulum.
Though I am kind of stuck, i need more things to write about and more equations i can calculate using the pedulum.
all i have so far is
E=mgh
H1=0.145m (90dgrs)
M=0.045kg
E=0.045x9.8x0.145
E=0.063945 J
1/m(v^2)
v^2=0.063945x2/0.045
v=1.685ms^-2
so that's the velocity of my first ball on 90 degrees.
and when that ball hit the ball on the other side went up 0.11m (11cm)
so;
H2=0.11
m=0.045
done same equations as before and got v=1.468ms^-2
so now i can only prove that the velocity changes to 1.468 from 1.685.
and that its inelastic because it changes, if you know what i mean.
i need more things that i can work with, more things i can try and find out with the pendulum. and how can i find out how long it will take before the pendulum will come to rest.
help anyone?
