The Easy Java Simulations Modeling and Authoring Tool is needed to explore the computational model used in the Sliding Down an Incline Plane Model.

A simpler version of the Inclined Plane model -- frictional force is removed.

changes made:

re-position to the hint texts
made the hint "change the angle of the slope and click play" to appear once only and playing and paused as other hints
re layout the model with my usual slider design and colored background
added stroke line to be dashed to represent components of gravity forces
made the auto-scale of y to allow angle up to 90 degrees.
added a scaleforce to draw the forces to user's choice

This interactive tutorial from The Physics Classroom collection offers extensive content support on how to determine the net force acting on an object on an inclined plane. It includes problems in which friction is present. Abundant use of free-body diagrams helps with visualization.

Physlet Illustration 5.1 covers frictional forces, and can be applied to the Sliding Down an Incline Plane Model.
