### Description

Introduction

In this lab, you are going to explore the motion of a ball set into projectile motion after falling off a ramp and bouncing on the floor. Classic projectile motion carries one simplifying assumption, which is that air resistance is negligible. Under that condition, the motion of the projectile can easily be analyzed by separating velocities and positions into their horizontal and vertical components.

INTRODUCTIONS:
This lab report contains information based on two masses being used in an apparatus known as
the Atwood’s Machine. The purpose was to measure the velocity of both masses they both move
in different directions due to their weight. There are objects that are heavier than others and
velocity changes depending on the masses of objects. This experiment we will be measuring the
velocity of two different types of masses. We will be utilizing an apparatus (known as the
Atwood’s machine) that contains a sensor measuring the velocity of both masses. We will be
adjusting the weights of both masses to see different results in velocity. We will be calculating a
theoretical acceleration and an experimental acceleration to compare both results to see if they
are identical. We hypothesize that we might get a percent error of at most 5% since the weights
may have minor air resistance that might have a slight interference with the force of gravity.

To set up the Atwood Machine, two hanging masses were changed to opposite ends of a string
on a pulley system. The two masses should be at least 40cm apart from one another to allow
adequate time for acceleration on both ends. A total of three trials were run. For trail 1, the mass
1 was bout130 g (or 0.130 kg) and 125 g (or 0.125 kg) for the mass 2. The total mass for the
system was 255g, with m1 always being heavier than m2. After the changes of tow masses, we
then start the simulation and record the result obtained. For trial 2, mass 1 is about 170 g and
165g for mass 2. For last trial (trial 3), mass 1 is about 200g and 195g for mass 2.
