Lab #6.3a
Mechanics: Chapter 6
Putting the Cart Before the
Horse
Purpose
In this activity, you will
observe the motion of a variety
of objects under a variety of
conditions. You will interpret
your observations to learn the
relationship between force,
mass, and acceleration.
Discussion
Some of the most fundamental
laws of motion eluded the best
minds in science for centuries.
One reason for this is that when
objects are pushed or pulled,
there are usually several forces
acting at once. To understand
the nature of force and motion,
it is necessary to observe the
effect of a single, unbalanced
force acting on an object. In
this activity, you will do just
that. You will also vary the
amount of force acting on the
object and you will vary the
mass of the object being acted
upon. Careful observations will
lead you to an understanding of
the relationship between force,
mass, and acceleration.

The computer
required for this lab is a PC
with Windows 98, 2000, Me, or Xp
which has a Pentium processor or
the equivalent and a USB port. A
Macintosh computer will also
work if the operating system is
Mac OS X (10.2 or newer).
Instead of a computer this lab
will also work with a Vernier
LabPro, CBL 2, or TI graphing
calculators. |
|
The "paper clips"
required for this lab are any
plain office paper clips you may
already have or are readily
available at your office or
school supply store. Each lab
would require one. The "books"
required for this lab are used
to level the ramp. Any books or
other material may be used to
accomplish this purpose.
