1. Go to https://goo.gl/RwTgyr
2. Select Friction from the choices as shown.
3. Check all the boxes in the top right as shown.
4. Answer the following questions.
a) Is the stationary friction of the box at least 100 N? Explain how you know.
b) Apply a total of 150 N of force. Does the box accelerate? How do you know?
c) Reset the simulation and check all the boxes again. Place the 100 kg garbage can on top of the box. Just by pressing the arrows, what does the applied force need to be to get the objects moving?
d) Write a statement that relates the mass of an object to the friction it experiences with the ground.
