"Objects At Rest Experiment 1"

Lab Report 1


Objective: The objective of this lab is to learn Newton’s law of motions.

Hypothesis: I think if you pull the ramp, the cart will move backwards on the table.

Materials: 1. wooden ramp
2. Cart

Procedure:
First, I had to set a wooden plank (the ramp) on a table with about 12'' of the ramp extended over the edge of the tables.
Second, I had to place the cart on the part of the wooden ramp that was on the table.
Third, I stood to one side and quickly jerked the ramp out from underneath the cart.I had to repeat step three 4 or 5 times and record my observations.

Data:
Trial 1-The cart did not fall or roll. It just slides onto the table Backwards.

Trial 2-The cart did the same thing it did in trial 1.

Trial 3-The cart slide off of the left side of the ramp.

Trial 4-The cart did the same thing it did in trials 1 and 2.


Conclusion: After we removed the ramp the cart did was move backward onto the table. My Hypothesis was correct just. Only thing is that it didn’t move.
I think that the cart did not follow Newton’s first law because his law states that a object at rest stays at rest. The cart was at rest on the ramp but when you moved the ramp the cart moves.

"Essential Questions for 11th Grade project"

1. I define a utopian society as a society that don't have no problems.

2. No because it will be hard to do that do to the all the crime rates and everything else.

3. Respect, freedom and freedom of speech.

4. People would want to live in a good place with no crime.

5. People might not like other people and that can lead to fights.

6. The consequence is to let people do what they want but in a peaceful society.

7. Yea a utopian society is attainable. A utopian society can cost a lot of money to me.

"AIDS In Nigeria"

I think this project was very good. The person who sit down and did it tooak their time.

"Tropical Storms in Fiji"

I thought this PSA had a lot of important information and it was good.

Bird Flu PSA

To me this PSA was really good. But one thing is that i didn't understand what they was saying.

Egg drop

The pros to this design is that it was more mapped out. The cons is that if you drop it hard the straw might break in half.
