During this experiment, I used a wooden block on different surfaces to examine the
concept of friction. Using a spring scale I observed the difference between static and
kinetic

Jessica Collier
July 18, 2015
For this experiment I used an inclined plane and a weighted marble to calculate the velocity and
acceleration at determined distances. This helped me calculate the average and standard deviation

The purpose of this exercise is to research the
different types of errors and how we can minimize
them in our measurements.

In this exercise, I used a 25 cm PVC pipe (resonance tube), tap water at room temperature, and a tuning
fork to calculate an estimated speed of sound. By moving the tube up or

1. The law is considered universal because her theorized that all mass, matter, and everything
else in the universe act in relation to one another. Every mass exerts a force on others
regardless of distance.

Introduction:
The purpose of this lab is to experiment with static and dynamic friction, and how the relationships of
different materials affect the force required to move an object and keep it in motion.

a. Mass would be measured in Kilograms while weight would be measured in Newtons.
b. Mass would be measured in Slugs while weight would be measured in Pound Force.

1. Impulse is a quantity of force multiplied by a time interval. Impulse is what causes an objects
change in momentum.
2. When a moving billiard ball comes into contact with a stationary ball, the principle of
momentum tells us that momentum will be conse

1. It is well known that objects expand when heated. An iron plate will get slightly larger
when put in a hot oven. Suppose an iron plate has a hole cut in the center. Will the hole
get larger or smaller when the plate is heated and expansion occurs?

Explain the difference between linear speed and rotational speed. Include formula difference and
how rotational speed is changed to linear speed:
The difference between linear speed and rotational speed can be seen in their
respective definitions. Line
