Basics HTML5 Part 2 – Friction. With 100%Verified Answers.
Name- -----

Learning Objectives: Students will be able to
• Predict how forces can change motion.
• Provide reasoning and evidence to explain motion changing or not.

1. Open the Forces and Motion Basics simulation and play with the Friction screen for a few minutes.




a. How does the Friction screen differ from the Net Force and Motion screens?
The friction screen is what shows you the direction of the force being applied, and
the way that it is being pushed or pulled according to the Newtons applied.


b. Also, what is something new you discovered?
I discovered that the friction force is always the opposite direction of the force that is
being applied. This example is represented in the Friction screen.

2. Imagine that your friend, Sam is trying to move a box.
a. Using what you learned by exploring, try drawing arrows to predict what might happen in
the pictures below. (Try this part without using the simulation.)




Sam not pushing Sam pushing but box Sam pushing and box moving
