Force of Kinetic Friction Pre-Lab

Purpose: To create graphical and mathematical representations of the relationship between the force of friction, the

normal force, and the types of surfaces.

• Open the Data Studio file Friction vs. Normal Force.

• Mass the loose friction tray and record below. Do not separate the plastic tray from the force probe!

• Remember to tare (zero) the force probe with nothing attached to it before your first trial.

Purpose: To create graphical and mathematical representations of the relationship between the force of friction, the

• Open the Data Studio file Friction vs. Normal Force.

• Mass the loose friction tray and record below. Do not separate the plastic tray from the force probe!

• Remember to tare (zero) the force probe with nothing attached to it before your first trial.

• Start with just the two friction trays, and then add 100 g = 0.100 kg into the friction trays for each additional set.

• Keep a single black bar mass on top of the constant velocity cart at all times.

• You must select the region of the graph for each trial that corresponds to the constant velocity part of the motion to measure the force of kinetic friction.
