Parallel Forces
Objective: Find FA and FB on the apparatus which are parallel to both Fulcrum A and B.

Calculations:
Theoretical FB
Στ = 0
+FB 0.5 - (0.1kg x g x 0.1m) - (0.2kg x g x 0.4m) - (0.05kg x g x 0.7m) - (0.1kg x g x 0.3m) = 0 -[{(0.1kg x 0.1m) + (0.2kg x 0.4m) + (0.05kg x 0.7m) + (0.1kg x 0.3m)}x 9.8] + 0.5FB = 0 0.5FB = [(0.1 x 0.1) + (0.2 x 0.4) + (0.05 x 0.7) + (0.1 x 0.3)]x 9.8 FB =

FB = 3.04 N
Experimental FB
FB = mpanB g - mfulcrumB g
FB = (0.385kg x 9.8) - (.0816kg x 9.8) = 3.77 - .800
FB = 2.97 N
Theoretical FA
-[(0.1kg x g) + (0.2kg x g) + (0.05kg x g) + (0.1kg x g)] + FA + FB = 0 -[(0.1kg x g) + (0.2kg x g) + (0.05kg x g) + (0.1kg x g)] + FA + 3.04N = 0 -4.41 + FA + 3.04 = 0
FA - 1.37 = 0
FA = 1.37 N
Experimental FA
FA = (mpanA x g) - (mfulcrumA x g)
FA = (0.205kg x 9.8) - (.0693kg x 9.8) = 2.01 - .679
FA = 1.33 N

Conclusion:
Since the distance of FB is greater than that of FA, the torque of FB is larger. The line of FA, lies directing on the 0.2 m axis, causing a torque of zero for FA. The theoretical and experimental values for both forces are very close, supporting the theory of torque and parallel forces.

Abstract
The purpose of this experiment, was to prove the concept of the uniform linear motion by using an air track. With this, we demonstrated the impulse and change in momentum, the conservation of...

...yields two integrations:
x = x0+v0t+1/2at2
v = v9+at
These two expressions show the relationship between position, velocity, and acceleration at a given time.
Newton’s 2nd law states that the acceleration of an object depends on the net force acting upon the object and the mass of the object. If there were no friction in this experiment, then the acceleration of the glider would be equal to acceleration of gravity multiplied by the angle between the air track and...

How does the length of a string holding a pendulum affect its oscillation?
Method
1. You will need the following apparatus: a pendulum, a piece of string, a clamp, a clamp stand and a timer.
2. Measure out 20cm and attach the metal ball.
3. Establish an angle and let the ball swing for 10 oscillations, timing it and stopping at the 10th one.
4. Write down your results.
5. Repeat steps 2-4 another 2 times so that your results are...

...concepts of energy and momentum conservation.
Conclusion
The purpose of the experiment was to investigate simple elastic and inelastic collisions to study the conservation of momentum and energy concepts. The objective of the lab was met since the validity of the Law of Conservation of Momentum was confirmed by determining the relationship of energy and momentum conservation between inelastic and elastic collisions by utilizing percent discrepancy...

Density
Abstract
This experiment was conducted in order to determine the density of the Aluminum metal samples provided in the lab. Specific tools such as the vernier caliper and balance scale were used to measure and record the values found. Given that density is a measurement of mass over volume, both of these quantities would have to be determined experimentally, prior to proceeding with...
