| - | One of the central features of Glowscript is being able to make objects that represent different things in the world. Making objects with Glowscript is much simpler than other languages and one of Glowscript's strengths. In this activity, you and your partner are tasked with using [[http://www.glowscript.org/docs/VPythonDocs/shapes.html|Glowscript's shape objects]] to write the word PHYSICS, Physics, or physics. | + | One of the central features of Glowscript is making objects that represent different things in the world.

| - | Making objects move across the screen involves a loop. This is typically a ''while'' loop that runs a block of code repeatedly until some condition is met (called "the loop control condition"). In this activity, you and your partner should create a box and a surface that represents a frictionless floor. The box should rest on the floor. | + | Making objects move across the screen involves a loop.

| - | Now that you have a working program that models the motion of a box over a frictionless surface, let's see what happens when to box then hits a rough patch. Add a piece of flooring to the end of the frictionless floor that is rough (make it a different color). When the box hits that patch it should now experience a frictional force. Model the motion of the box as it moves across the frictionless floor and into the rough patch. You are free to choose relevant parameters. //Make sure to comment each line of additional code you write.// | + | Now that you have a working program that models the motion of a crate over a frictionless surface, let's see what happens when the crate then hits a rough patch.
