1. What are the relationships between forces and motion?
The relationships between forces and motion is the newtons laws. The newtons laws often involved an object in motion staying in motion. unless acted upon by an outside force. This shows how forces and motion have to intertwine or else objects would just stay in endless motion. That is the relationships between forces and motion.
2. What are the variables that affect motion and force?
the variables that effect force and motion would be gravity. Gravity because it causes friction and thus is an outside force affecting the motion and force of the object. This of course would also count frtiction as a force of motion and thus is also an effecting variable. BOOM
3. How does Newton’s three laws describe the motion of a moving
object?
That an object in motion should tend to stay in motion. That an object also in motion tends to stay in motion unless activated by an outside force. also that an object that is not in motion will stay still.
4. How does gravity impact objects?
gravity causes friction within the objects and the force. this causes the object to slow down. This labels them as an outside force which makes the object stop, also gravity pushes down on an object.

lab report race car thingamabob
at the start of the experiment we set up a board at an angle which allowed us to race the cars at a downhill angle. after we raced the car without the weights we added weights starting with a small weight, moving to a larger amount. After we reached the maximum weight we graphed the equation and we found that the friction increases with the amount of pressure and mass added on by the weights which caused the car to slowdown. we then answered some questions and graphed the equation

museum of science field trip.
our physical science class recently took a trip to the Boston Museum of Science. this blog is an overall review of our experiences and what we learned about friction, movement, and electricity.
while we were in the museum we saw the Fantastic Forces Presentation. which was meant to educate us on the laws of motion, and friction. we observed the forces of movement take place, for example we saw a pressurized pencil going at 100 miles per hour go through a block of wood. I also l learned that Newton was the scientist who figured out gravity. even though in my opinion everyone already knew what happens when an apple falls out of a tree. he just gave it a name.
shortly after the presentation we went to see the rolling ball sculptures which was made by George Rhodes not just for Boston, but for other museums as well. however, the ball, driven by gravity drops down triggering several musical instruments. for the most part however, the ball just went down because it was driven by the forces of gravity. which caused the ball to go down which triggered the instruments making several sounds and noises. that was all of the sculp0ture.
after that we went on to a class on engineering and we built bobsleds. my bobsled got a time of 1.36 seconds which was one of the fastest while albert won with 1.33 seconds. my bobsled had a leopard print kind of cloth on top of it. it also had two batteries to make it go faster. I ended up not naming it because I don't like naming thing after we completed the engineering course we went to see my favorite part of the museum,.
we saw the electric show. it showed us how powerful electricity really is. they used electric pulses to make the musical notes from star wars, and other musical numbers. they also used electricity to make peoples hair rise and explained to us what to do in a lightning storm. then for the finale the scientist who was running the whole thing went into a completely metal cage. then he mad the cage be electrocuted with what I can only imagine to be hundreds of thousands of bolts of electricity. that was the conclusion to the experiment and really to the field trip.

chemical reactions
experiment one
we started the experiment by steel wool and setting it on fire. after setting it on fire it turned a bluish color from the grey.
experiment 2.
we then proceeded to use baking soda and we used the NaH203-h20=co2 thus making it burn and it decomposed into the flames.
we then di the nail and copper sulfate which caused the copper to bubble . we also did this on zink

the periodic table is shaped like a castle, with the left side being mostly metals and the right being gases. the only acception is hydrogen which is listed as a metal. most of the metals and gases are made into chemical symbols like oxygen is just O and helium is HE these chemical symbols make it a lot easier to determine which metal/gas it is. there is also the affects of the atomic number which s listed below each of the chemical symbols. then there is the mass of each which shows how each each one weighs on the table. the table is also divided into groups and periods. the groups are the vertical sections of the periodic table where the periods are parallel. the periodic table is organized into whether or not it is a metal or a gas. there are also more specific parts to the metals and gases like alkaline metals and noble gases. there are also the electron affinities, which is the electronic power, ionized energy which is the amount of ionic energy per chemical symbol, and atomic radius which does what it says it does it shows the atomic radius, ionic radius which shows the ionic radius, and electronactivity.

flame lab
this week in our class we did a lab on the reorganization in chemical reactions In the release of absorption of heat energy. the chemical formula would turn the chemicals into a different color. like yellow, red, purple, and sparked. in the sr lno327 chemical caused the flame to turn yellow. the only real inaccuracy would be if you used too much of the chemical formula on the flame. it was easy to figure out the element based off of the color of the flame. the flames on the chemicals are produced by chemical reactions from the heat energy. I think chemicals have to be heated by chemicals.
