Another Planet

You have landed on another planet that you live and breathe on (just like Earth!), but it is TWICE as big as Earth.  Create a blog post naming and describing your planet.  In this description, be sure to include a comparison and contrast to the gravity that we have here on earth.

               My planet is called unearth. My planet would have more houses then apartments. My planet would be green with no pollution. My planet would be clean with no trash anywhere and my plant would have more trees unlike earth that you see more apartments and you  barely see trees and everywhere you walk you see trash on the streets. The gravity on my planet is a little more then the gravity on earth so the weight of everything will weight more.

Electric light

Write a blog post completely describe today’s Light the Bulb activity, then explain why you think the light bulb lit up. (How do you think the electricity works to light it up?)

Today we try lighting a light bulb with a wire  and a battery. with one end of the wire you have to put it at the bottom of the battery and the other end of the wire you have to put it on the side of the light bulb and then you have to put it on top of the battery and has to be like a circle so the electric can move. I think that the light bulb light up because the electric needs a flow to pass through the wire around.

“Work vs. Power”

Explain (in your own words) the difference between work and power.  Give an example showing work done with a lot of power and then with a little power.

My understanding of work is a amount  of force you put on a object to move it a distance. Power is the rate which work is done.


Pulling a item up a hill slow and then pushing the item down the hill you would be using a lot of power but dropping the object from the top of the hill is using a little power.

“Balanced and Unbalanced”

Find an example of two free body diagrams, one that is balanced and one that is unbalanced.  For each, describe the forces that are on them and what makes them balanced or unbalanced.


A balanced force is when the net force is equal to ZERO. A unbalanced force is when the net force does not equal to ZERO.

“Free Body Diagrams”

Post a picture or provide a link to a Free Body Diagram you found on line. First, describe what the object is and how it is moving.  Then NAME and DESCRIBE each of the forces that are shown on the diagram.  Make sure your picture is visible once published (or provide a link).




The object is the book and the book has  gravity and normal force. The book has Fg because the book is being push down but the book has Fn as well  because the book is not accelerating downwards.

Friday, November 7-“Vectors & Scalar”

Explain the difference between vector and scalar and find an example of each that we did not cover in class (you can use the internet or pull from your own life)
The difference between vector and scalar is that vector is a quantity that shows direction.
A airplane is vector because it uses direction and acceleration.

Thursday, November 6- “Four Forces”

Describe each of the four types of forces that we did in class in your own words.  For each one, give the description and an example of it in your life

applied force -is when you moves because a person or thing push or pulls something

gravitational force - when two objects are pulled together and one object is earth

normal force - when a surface is being pulled by gravity

tension force -  when a string is pulling an object.
