The Team
Introduction
The goal of our project was to build a
device to raise a 1 kg mass to a height
of 1 m in 10 seconds.
 All of our parts were purchased at
Lowe’s. Others were very easy to find
household items.

Overview
Ball goes down Chute
 Ball hits the Hinge
 Hinge lets go of string
 String loosens
 Allows the Water Bottle to raise the
weight to a height of 1 m

Energy Conversions

Ball
 Gravitational Potential Energy to Kinetic
Energy

Door Hinges
 Kinetic Energy to Spring Energy

Water Bottle
 Gravitational Potential Energy to Kinetic
Energy by way of Atwood’s Machine
Conclusions
Our project took about 3 hours to build
and plan in its entirety.
 Problems Faced:

 Getting the hinges to stay horizontal
 Getting the structure to be stable
 Getting the device to actually work
