Lab II, Problem 1: Mass and Acceleration of a Falling Ball

Physics 1301W, Professor: Paul Haines, TA: Aaberg, Arthur A
Team members: Yutong Li, Johnathan, Henry

Abstract
The mass of the ball should not have any influences on the acceleration when the ball is in free- falling. Balls in same size but not the same masses will fall down in the same height.

Introduction
The National Park plans to use the spherical canisters filled with fire-retarding chemicals to help fight forest fires. Because the chemical inside of the canisters are different, the canisters are varying in different masses. In order to drop the canisters accurately, I have to explore the influences that the masses on the acceleration of the canisters.

Prediction
We predict that the canisters’ acceleration will not be influenced by the different mass of the canisters. The force which will act on the canisters should be just the gravity force. a=g Procedure
I used a baseball and a plastic ball to pretend to be the different kinds of canisters (the same size=7cm). Then, I dropped the two different balls at the same height: 80cm in two different times. Jonathan used the camera to record the process that the two different balls falling down in two different times. Then, Henry used the graphing tool on the computer to draw the Position VS Time graph and Velocity VS Time graph by using the data we collected from the video records of 2 different balls.
Data
The graph of the baseball’s position VS time

The graph of the plastic’s position

Lab Report Format

ANATOMY & PHYSIOLOGY CLASS: WRITING LAB REPORTS The following is an explanation of the format that is to be used for writing lab reports. There will be lab activities for each Chapter in the textbook. 1. Lab Report grades are given the same value as a test grade. It is very important that they be done correctly and thoroughly. 2. All lab reports should be typed using Times New Roman and only 12 font. (no exceptions) 3. In the upper left hand corner include your name, high school, and A & P…

Drosophila Lab Report

Drosophila Lab Report By Logan Aker University of Colorado, Boulder Principles of Genetics Lab, MCDB 2151, Tuesday 4 – 5:50pm TA: Alexander Martinez Abstract In this lab, we carried out two different crosses using Drosophila; a monohybrid cross and a sex-linked cross. This lab specifically tested Mendel’s laws of independent assortment and the law of segregation in genetics. We selected males and females of two different phenotypes and mated them (and their succeeding offspring)…

Momentum Lab Report

Lab report #5 In this experiment, we used a nearly frictionless surface to compare velocity characteristics to that of momentum, suing different weights, as well as bouncing carts and sticking carts together. This is important to understand, because momentum is a combination of weight and velocity, where as velocity is independent of weight. The materials we used for this experiment include 2 carts, with weights of 139.7 grams and 290.4 grams. We also used springs on the ends to “bounce”…
