Students use precompiled data to determine the relationship between the component of an object's weight that is parallel to an inclined plane (Fpar) and the angle of the plane.
Students study the forces acting on a block resting on an inclined plane. They first study a diagram of the forces acting on the block.
Next, students change the angle of the plane and observe how the length of the parallel force vector changes.
Finally, graph the ratio of the parallel force to the block's weight vs. the angle of the plane. They identify the relationship between the two forces (i.e., Fpar = Fg sin θ).
