Marble Launcher Lab Sources Of Error

To avoid this error chemists should perform tests on an entire population size.

Marble launcher lab sources of error.

I ll assume you are using simple lab equipments and that the experiment involves dropping the ball from fixed height and measuring th. In this experiment you will be using the marble launcher to project the marble at different angles and speeds. I did a lab experiment based upon projectile motion. The type and number of errors depend on the setup of the experiment and the measuring devices that you are using.

Also list what you think will be the sources of systematic errors in this experiment. 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. We took a marble put it on a ramp and let it roll along the table and off the table. Marble launcher marble tape measurer ruler procedure.

It will launch a small marble about 1 5cm in diameter. This gave a time of 0 416 s. Do not list all possible sources of errors there. Marble launch lab purpose.

The goal was to predict where it was going to land and place a cup there. Using the kinematic equations you can calculate the marble s initial velocity as it leaves the table. You are going to launch the marble from the same height 10 times and measure its horizontal range. Q1 questions about where the center of masses are using integration with solution.

List what you think the sources of random errors will be in this experiment. Where d y is the distance in the y direction and g is the acceleration due to gravity 9 80. Range and initial velocity of the ball. What are some possible sources of error.

First set the launcher so it aims at an angle of 0 degrees. 201 understanding gravity lab rev 0917 in class work and energy last chance circular motion work and energy collisions 1. Physics 31210 lab 2 study i. 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.

One i thought of is that the table is not completely level and that means. For example if the lab table is not perfectly leveled then for the collision experiments m6 impulse and momentum when the track is supposed to be horizontal results will have a large significant. November 7th 2011 abstract we created a projectile launcher out of materials found at home. 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.

Physical variations can also account for errors in the chemistry lab.
