Marble Launcher Lab Sources Of Error

In this experiment you will be using the marble launcher to project the marble at different angles and speeds.

Marble launcher lab sources of error.

Also list what you think will be the sources of systematic errors in this experiment. Where d y is the distance in the y direction and g is the acceleration due to gravity 9 80. You are going to launch the marble from the same height 10 times and measure its horizontal range. Using a projectile launcher to verify that increasing the initial angle increases the range thanoja gnanatheevam yadesh prashad saad saleem mai wageh and timothy yang.

It will launch a small marble about 1 5cm in diameter. November 7th 2011 abstract we created a projectile launcher out of materials found at home. Chemists can usually prevent these types of errors by discussing the experiment with peers beforehand as others might point out flaws that the chemist does not see. Using the kinematic equations you can calculate the marble s initial velocity as it leaves the table.

Physics 31210 lab 2 study i. Physical variations can also account for errors in the chemistry lab. We used knowledge of projectile motion to predict the landing point. Your goal is to identify only those significant for that experiment.

Q1 questions about where the center of masses are using integration with solution. Determine the potential energy stored in a spring as it is compressed different distances by finding the horizantal distance the ball travels and solving for velocity. Using the initial elevation as the distance traveled in the y direction the time was found using the following equation. We took a marble put it on a ramp and let it roll along the table and off the table.

What are some possible sources of error. 201 understanding gravity lab rev 0917 in class work and energy last chance circular motion work and energy collisions 1. To avoid this error chemists should perform tests on an entire population size. The type and number of errors depend on the setup of the experiment and the measuring devices that you are using.

The goal was to predict where it was going to land and place a cup there. First set the launcher so it aims at an angle of 0 degrees. I did a lab experiment based upon projectile motion. This gave a time of 0 416 s.

Do not list all possible sources of errors there. Marble launch lab purpose. I ll assume you are using simple lab equipments and that the experiment involves dropping the ball from fixed height and measuring th. One i thought of is that the table is not completely level and that means.

List what you think the sources of random errors will be in this experiment.
