Science – Lab Report

1. Introduction

In this lab, Shannon and I were investigating the affect of different materials on the force of friction.  Our question was how do different sliding surfaces affect the friction of objects.  The physical property of different surfaces affects the amount of friction that results when they encounter each other.  The greater the friction force between the two surfaces, the greater the force needed to cause motion.  With this being said, I think the smoother the surface, the less friction the surfaces will have when they are in contact, causing the object to move quicker.

This experiment can be applied to a real-life situation.  The friction between the tires of your automobile and the road determines your speed.  Depending on the weather conditions or the material the road is made of, can affect your speed.  When it is raining, your car tends to go faster because you have a layer of water lubricant under your tires.

Middle

The first surface we tested was the construction paper.  We laid the construction paper on the table, an inch away from the pen.  Then we placed the block on top of the paper.  The cup was now hanging over the table edge.  We began to add small washers until the block began to move.  Once the block began to move, we started the experiment.  We started the stopwatch and let the block slide across the surface.  When the block hit the pen, we stopped the stopwatch.  We repeated the same steps for the other four surface areas: granite, felt, tabletop, and Styrofoam.  We recorded our data in a table.

1. Results

Before beginning our experiment, we attached a plastic cup to the block of wood and added washers to it.  The washers acted as weights.  Beforehand, we weighed one washer to get the weight.   Each washer weighed 15.1 grams.  After calculating the weight

Conclusion

I think a few errors were made in the experiment.  I think the placing of the block of wood should have been more precise.  I think timing also could have been more concise.  For future experiments, I think there should exact measurement where the block should be placed and the person using the stopwatch should be more careful and concise while timing the experiment.

If both were present, they could theoretically cancel each other; however it is also possible that they could have both contributed. In order to attach a percentage error to the angle at which the light gate was in comparison to the angle of the ramp, it was necessary to measure the angle of the light gate.

2. ## What Affects the Strength of Magnetism Exerted By an Electromagnet?

Thus, a greater field is produced. It must also be inversely proportional to 'The Square of The Distance From The Charge'. This means that the field strength should get reduced as we move away from the charge. Fundamentally, a current produces a magnetic field due to the current consisting of many charges moving, each charge producing a magnetic field.

Using this process, reservoir heterogeneity capturing is attempted; this is done by matching fractional flow curve through manipulation of permeability field. The second step involves mapping the modification performed to the streamline permeability on to the grid blocks. Flow simulations are performed to check match, in which iterations are involved if desired match is not achieved.

We tend to believe that though they may travel at a very high speed, that speed is not limitless. Einstein illustrated the basic idea of general relativity with an imaginary experiment. Suppose a lift is at rest in space. If a ball is released within the lift, it will float in space and not fall.
