Part A.
In this lab, we will explore the relationships between work, kinetic
energy, potential energy, and even power through some makeshift
pulley systems.
In you lab kit, you should find thread, the ping pong ball and marble,
and the measuring tape. You will also need tape to adhere your thread,
to both balls and a timer. You will need to adjust your set up, so make
sure your tape can be removed.
Find furniture in your home you can use to set up the pulley system
pictured to the right. Ideally, both the marble and ping pong ball would
be able to hang freely without any normal force acting on them.
First, we will bring the heavier ball close to the top of our pulley system and allow it to fall,
pulling the lighter ball up a distance. We will then calculate the work done by gravity on the
heavier ball and the potential energy gained by the lighter ball. In order to do this, we must
measure some quantities first. Fill in the table below with your measurements.
