Scenario
a ball falls from rest from a height h. consider the
ball to be the system.
using representations
part a: draw a dotted circle around the system
part b: the dot at right represents the ball. draw a free-body diagram
showing and labeling the forces (not components) exerted on the
ball. (this should only include forces exerted on the system.) draw
the relative lengths of all vectors to reflect the relative magnitudes of all
the forces. each force must be represented by a distinct arrow starting
on and pointing away from the dot.
part c: on the grid below, sketch a graph of the net external force on the ball
vs. height. what are the units of the area under the curve?
what does the area under the curve represent?
height
net external force
