Module 2 Discussion MMT

Instructor:

Each student will create a problem or experiment, illustrating one of the concepts covered in this module, and share it in your initial Discussion Board posting. A template for both of these posts can be found in my online office and course syllabus. You must make your initial 250-word post a reply of at least 200 words to the initial posts of two or more of your fellow students.  The instructor will be actively engaged and contributing to the Discussion Board activities throughout the module.  Points will be deducted for poor grammar, misspelled words, improperly cited web/textbook references, late initial posts, and posts made all at one time (do not “post and run”).  Posts made after the end of the module will be reviewed by your instructor, but you will not get any credit for them.  In addition to your individual posts, the instructor will post questions relative to the topics being covered in that Module. Each student is expected to respond to those questions in addition to the posts described above.

Students:  You will receive no points for a plagiarist post of material and/or the majority of the post is not original work (in your own words—i.e., cut/paste content from a website or paper).

According to Newton’s first law, an object at rest (not moving) will remain at rest unless acted on by an unbalanced force. Also, an object in motion will continue to move at a constant speed in a straight line unless acted on by an unbalanced force.

When a rocket is sitting on the launch pad and not moving, there are forces acting on it, but these forces are balanced. This means that the force pulling it downwards (gravity) is equal to the force pushing it upwards (support force of the ground). These forces are balanced. The rocket will keep on not moving, as described by Newton’s first law.

For an object to start moving, there needs to be an unbalanced force. This means that the forces pushing an object in one direction are greater than the forces pushing it in the opposite direction. The resultant force is the difference between the force(s) pushing in one direction and the force(s) pushing in the opposite direction.

Some questions I’d like you to think about:

1.      A rocket will launch and keep speeding up as long as? (Think about all the forces acting on the rocket)

2.      There are two forces acting on a rocket at the moment of lift-off. What are they?

3.      As the rocket increases speed, there is a third force on the rocket that begins to increase. What is it?

4.    Once the thrust from the rocket engines finishes, the resultant force is now what direction?
