• Learn where the controls are to change objects,
  add/remove friction
• Learn where the controls are to change the
  friction coefficient

Create the following set up

• Crate
• Original position 0
• Graph Acceleration (and Force)
• No Friction
• Applied Forces
• Push the crate with any force so it starts to
  move to the other end. Use your playback and
  pause button to find your HIGHEST force and
  acceleration it took to hit that force type that
  data into the next slide.

Is the ratio of the force to the acceleration
constant? If so, what does this tell you about
the relationship between Force and
Acceleration?

• Add Friction, check the controls, and set the
  value to 0.2 for static and kinetic friction,

Does friction help motion or oppose motion
(acceleration)?
