YOUR CHALLENGE
Your first challenge is to calculate the coefficient of kinetic friction on an inclined plane using
the GLX explorer. Using the GLX, a force meter, a wooden block with string, a retort stand with
support bar, and an inclined plane (MDF board), determine the coefficient of kinetic friction
between the block and the board. The wooden block is connected as shown in the diagram
below. This will be done in two ways. The first step is to calculate μ going up the track and the
second involves calculating μ going down the track. During both steps, you should try your
best to allow the block to go up and down the incline at a constant velocity.
(NOTE: Use an angle 30° or greater)

YOUR CHALLENGE
Your second challenge requires you to calculate the coefficient of kinetic friction of the wooden
block as it accelerates up the incline. The wooden block is connected at an angle to a hanging
mass as shown in the diagram below. Using the Explorer GLX, a motion sensor, a wooden block
with string, a pulley, a c-clamp, a retort stand with support clamp, and a hanging mass (200g),
determine the coefficient of kinetic friction as the wooden block accelerates up the inclined
plane. (NOTE: Use an angle 30° or greater)
