Acceleration, Mass, and Force?! Ahh

This week we took what we learned in class last week and expanded on it. We learned that the direction of the unbalanced force is the same as the direction of acceleration, and that the bigger the mass the smaller the acceleration and vise versa. We made a few force diagrams for examples.

May The Force Be With You....

Hello!!!! This week in science we started to learn about force. Not the force as in Star Wars (though that would be cool...) but in physics, force is what changes a state of rest or motion in an object. Force causes objects to accelerate or change direction. Force is measured in Newtons. (N) We made force diagrams that show how different forces affect an object. In life it helps us understand why some things rise or fall. For example a with a ball sitting on a table, the earth is pulling the ball down but that table pushes it up so it doesn't move. Let's say the force of the earth is 10N, same as the table. The number sentence would be (10N)+(-10N)=0N because the object is not rising or falling. Thanks for listening! Come back next week for some more exciting science! May the force be with you...

Slopes & Functions

This week in science we worked on finding slopes and writing functions. If a man is walking at 4 meters in every 2 seconds and he starts at 0 for position, where will he be after 10 seconds. The slope would be position over time, so 4/2 and the slope (or speed) is 2 meters per second.The function to answer the question would be x(t)=2(m/s)*t. To solve it you put in 10 for t. x(t)=2(m/s)*10. The answer for x would be 20. So, at 10 seconds the man would be at 20 meters.

Science; Motion Is Relative

Hey everyone! This week in science class was very interesting, and I feel like I can understand the world around me a little bit better. We have been learning about motion for the past week, and how some things can appear to be moving in different directions for different observers depending on their position and/or if they are in motion themselves. For example, if the observer is moving at the same direction and pace as the object, it will not appear to be moving. But, if someone else is standing completely still, the object will be moving to them. To test this, one student, Laura, stood on a desk. For all of us that were sitting in out seats, she was not moving. To Mr. Segen, who was walking across the room, it looked like she was moving. This is why motion is relative to the observer.

Hello World!

This is my first blog and it rocks!
