Lab #9.1
Mechanics: Chapter 9
An Uphill Climb
Purpose
In this experiment, you will
determine what advantage—if
any—there is in using an
inclined plane to move an object
to a higher elevation.
Discussion
Why are ramps used when lifting
heavy objects? Does it make the
task easier (requires less
force)? Does it make the
movement shorter (requires less
distance)? Does it make the
effort more efficient (requires
less work)? Perhaps it does
several of these; maybe it does
none of them. In this
experiment, the cart will act as
the heavy object. Your task will
be to move your cart a vertical
distance of 20 cm above the
tabletop. You will arrange a
series of ramps (inclined
planes) at different angles to
accomplish this task. You will
measure the force needed to move
a cart up the incline. You will
also measure the distance
through which that force would
be applied to finish the job.
You will then calculate the work
required to lift an object using
an inclined plane. By the end of
the experiment, you will be able
to identify what an inclined
plane can do for you in terms of
force, distance, and work.
