several objects.
Discuss how work input is
transformed to other types of
mechanical energy for various
scenarios such as a car on a
roller coaster and a swinging
pendulum.
Students will pull a brick up an
inclined plane, and measure the
amount of applied force, length
and height of ramp, and the
weight of the brick.
Students will ascend stairs at
different velocities and measure
time, height of stairs, and
weight of student.
Students will pull a brick up an
inclined plane, and measure the
amount of applied force, length
and height of ramp, the weight
of the brick, and the time for
each trial.
work done on each object and
compare the amount of work
done to the applied force and
the distance traveled.
Students will specify the source
of mechanical energy input for
various systems.
Students will analyze of
efficiency of the inclined plane.
Students will determine the
work done and the power for
each trial.
Students will compare the
power to the efficiency for each
trial.

2. Energy has a source, can be transferred, and can be transformed into various forms but is
conserved between and within systems.
