Using Freezing-Point Depression to Find Molecular Weight Formal Lab Report
The purpose of this lab is to be able to use the freezing point of a substance to find the molecular weight of it. To do this, we will use the Logger Pro program to obtain the freezing point of lauric acid and...

Lab Report 1: Cell Transport Mechanisms and Permeability Using PhysioEx 8.0
The purpose of these experiments is to examine the driving force behind the movement of substances across a selective or semiperpeable plasma membrane. Experiment simulations examine...
The lab of one dimensional motion is a series of experiments that deal with different types of motion in a single direction. In the first experiment, one dimensional motion of a small cart on an air track is measured in a one photogate system. The acceleration was calculated by the infr...
Hypothesis: For an increase in a normal force, there will be a corresponding increase in friction.
Introduction: Force is usually connected with a push or pull exerted on an object. In this experiment, I am using a contact force, a force that exists from physical contact between two things. I...

Experiment 1 Pure Bending of a Beam
Experiment 2 Torsional Deformations
Experiment 3 Yield Criteria for Ductile Materials under Plane Stresses
In this experiment, we were trying to find the relationship between the amount of force and acceleration of an object. We used Force, Acceleration, Distance, and Weight to find these figures.
The procedure involved setting up the pulley for the weights, and adding weights to...

A. Plant and Animal Cell Diffusion and Osmosis
In this experiment we observed carmine powder to better understand the concept of Brownian motion and the role of molecular movement in diffusion. The particles continuously moved in a co...
1. Take 0.02 Kg from the top of the cart and place it at the end of the string. The weight of this mass is not balanced by the table and will cause the cart t o be accelerated. Find Fnet and record this number in Table 1a.
2. Position the cart at its starting position and using...
