Newton’s Second Law: Constant Force
What happens if the cart is pulled by a constant force? Arrange the CI-
6742 Motion Sensor, CI-6537 Force Sensor, and cart on the track as in
the previous suggested experiment. Set up a pulley, string, and hanging
mass so that the cart/Force Sensor will be pulled by the string attached
to the hanging mass. Use the Motion Sensor to measure the velocity
and acceleration of the cart as it is pulled by the string. Use the
computer program to compare the measured force to the measured
velocity and acceleration. Change the hanging mass and repeat the
experiment.
Work Energy Theorem: W =
∆
KE
What happens to the kinetic energy of the cart as it is pulled by a
constant force? Arrange the CI-6742 Motion Sensor, CI-6537 Force
Sensor, and cart on the track as in the previous suggested experiment.
Set up a pulley, string, and hanging mass so that the cart/Force Sensor
will be pulled by the string attached to the hanging mass. Use the
Motion Sensor to measure the change in position and the velocity of
the cart as it is pulled by the string. Use the computer program to find
the integration under the curve of a force versus distance graph. Use
the program to calculate the amount of kinetic energy gained by the
cart. Compare the calculated value of the work to the calculated value
of the final kinetic energy.
