Newton's Laws I
To investigate, qualitatively and quantitatively, the motion of an object when acted upon by
Motion sensor, force sensor (2), Pasco track, Pasco cart, hanging masses w/built-in hooks
(2), short looped string for one motion sensor, meter stick, wooden blocks (for elevation)
You are already familiar with
, the study of motion that does not take forces and masses
In this lab you will find relationships between forces,
masses and the resulting
motion; this branch of mechanics is called
For these series of experiments, do not take
what you have learned from your lecture or textbook for granted - do the experiment and form your
Use the cart, track and a pen to determine a
relationship between an object's direction of
motion (define one direction as (
), the other (
Examine the cart while it is at rest (not hitting or
tapping cart), in motion, in motion but being tapped constantly on one side with a pen.
Fill in the table
below with either 0, + or -, depending on whether the quantity listed is zero, to the right, to the left.
"Change in motion" is slowing down or speeding up.
For instance, if the cart was moving to the right
(+) but slowing down, the Change in Motion would be (-).
If the net force was to the left, put a (-) in
