Newton's First Law
An object at rest, or in motion, remains at rest, or in motion, until acted upon by unbalanced outside forces
- derived from Galileo's concept of INERTIA.
- An objects resistance to a change in motino is called Inertia.
- Inertia is a property of mass and cannot change. Thus the more massive an object is, the more inertia that object has.
In other words, objects at a constant speed in a given direction remain at a constant speed in that same, constant, direction until accelerated by unbalanced outside forces.

Reading:
The Physics Classroom is a great web resource for working on elementary physics, especially Newtonian Mechanics, a.k.a. Newton's Laws.
- Go to the website above (The Physics Classroom).
- Read each section under Newton's 1st Law (inertia and mass, state of motion, balanced and unbalanced forces).
- Visit this simulation and toggle the thrust in order to land your spacecraft softly and safely.
*If the simulation does not work at first, then enable java script on your browser. If you cannot do this, ask me for specific instructions on doing so. If the problem persists, then download the file and run from your desktop.
Blog:
- Compile a list of questions or concerns you have regarding the reading and post them to your blog explaining your ideas to the best of your ability.
- Discuss how the simulation relates to Newton's First Law.
- View at least three of your classmates' and comment on at least three questions.
Positive and constructive responses only!
Here are two videos one regarding Inertia; the other, mass.
Watch the video and think about how Newton's 1st Law applies to everday life.

Assignment 1:
Write a one-act dramatic comedy, a dramedy. Brainstorm Newton's Laws. Choose an idea. Your one-act dramedy may NOT be any longer than five minutes. Your assignment will not be accepted ifit is over five minutes (5:01 or more is not acceptable). You may choose to eithr conduct you act live in front of the class, or you may present your one-act drmaedy by video. The only constraints are that your one-act pertain to Newton's First Law and it may NOT be any longer than five minutes.

Creative way of keeping your attention.

Certainly not a dramedy, though quite creative and definitely dependent upon Newton's Laws of Motion.
