Range and initial velocity of the ball.
Marble launcher lab sources of error.
201 understanding gravity lab rev 0917 in class work and energy last chance circular motion work and energy collisions 1.
What are some possible sources of error.
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.
First set the launcher so it aims at an angle of 0 degrees.
The type and number of errors depend on the setup of the experiment and the measuring devices that you are using.
We used knowledge of projectile motion to predict the landing point.
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.
It will launch a small marble about 1 5cm in diameter.
List what you think the sources of random errors will be in this experiment.
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.
November 7th 2011 abstract we created a projectile launcher out of materials found at home.
I ll assume you are using simple lab equipments and that the experiment involves dropping the ball from fixed height and measuring th.
Physics 31210 lab 2 study i.
Physical variations can also account for errors in the chemistry lab.
We took a marble put it on a ramp and let it roll along the table and off the table.
Your goal is to identify only those significant for that experiment.
One i thought of is that the table is not completely level and that means.
Q1 questions about where the center of masses are using integration with solution.
I did a lab experiment based upon projectile motion.
The goal was to predict where it was going to land and place a cup there.
This gave a time of 0 416 s.
You are going to launch the marble from the same height 10 times and measure its horizontal range.
Do not list all possible sources of errors there.
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.
Where d y is the distance in the y direction and g is the acceleration due to gravity 9 80.
Also list what you think will be the sources of systematic errors in this experiment.
Using the kinematic equations you can calculate the marble s initial velocity as it leaves the table.
Marble launcher marble tape measurer ruler procedure.
To avoid this error chemists should perform tests on an entire population size.
