Lab Assignment: Forces and Friction Laboratory: Description
Developing a Hypothesis:
The two basic kinds of frictional forces are static friction and kinetic friction. Each of these kinds of friction can be characterized using a coefficient of friction— 
for static friction and 
for kinetic friction. In this laboratory, you will measure the coefficients of friction and calculate the force using the equation F = m a.
Create a hypothesis of what you think will be the results of this experiment.
- How will the coefficient of static friction compare to the coefficient of kinetic friction?
- What happens to acceleration if the force acting on an object is increased?
Defend your hypothesis with your knowledge of forces. Your answers will be part of your lab write-up that you submit to your teacher.
Objectives:
- Compare the coefficients of static and kinetic friction for the wooden and glass surface.
- The value of the static friction force and kinetic friction force increases with the weight (Normal force) of the blocks, but the coefficient of static and kinetic friction remains the same for the given surface.
- Evaluate the relationships between mass, acceleration, and force.
