Friction Lab
Use hand sanitizer or wash your hands and collect the following materials.
Materials:
Friction board
Spring scale
mass
small container
Examine and describe the four different surfaces. How they look, how they feel, what the surface is like.
Watch the video and record the newton's required to make the boat move across each strip.
Report the Newtons required to start the mass moving across the sand paper strip.
Report the Newtons required to start the mass moving across the black mat.
Report the Newtons required to start the mass moving across the cork.
Report the Newtons required to start the mass moving across the paper.
Which material required the most force?
Which material required the least force?
What type of friction is preventing the mass from moving at the beginning?
What type of friction is opposing the motion after the mass begins to move?
Reflecting on your description of the materials, why do you think you obtained the results shown above?
