1. Sciencefinal project<br />E.Q 1:what is the difference between velocity and speed? <br />
2. What is speed ?<br />Speed is how fast something is moving.<br />3/4/2010<br />math<br />2<br />
3. What is velocity ?<br />Velocity is speed in a specific direction.<br />3/4/2010<br />math<br />3<br />
4. Speed<br />Speed is distance over time, because the distance you are going and the time.<br />3/4/2010<br />math<br />4<br />
5. velocity<br />In velocity you always have to have speed , directions , and time but you don’t have to have mass.<br />3/4/2010<br />math<br />5<br />
6. E.Q 2:what is simple machines<br />A simple device that makes work easier for you to do. such as a lever, pulley, or inclined plane.<br />3/4/2010<br />math<br />6<br />
7. What is a lever ?<br />a rigid bar pivoted on a fixed point and used to transmit force, as in raising or moving a weight at one end by pushing down on the other.<br />3/4/2010<br />math<br />7<br />
8. What is a pulley?<br />essentially of a wheel with a grooved rim in which a pulled rope or chain can run to change the direction of the pull and thereby lift a load.<br />3/4/2010<br />math<br />8<br />
9. What is a inclined plane?<br />A plane set at an angle to the horizontal, especially a simple machine used to raise or lower a load by rolling or sliding, and it cause you change directions.<br />3/4/2010<br />math<br />9<br />
10. What is a wedge<br />A piece of material, such as metal or wood, thick at one edge and tapered to a thin edge at the other for insertion in a narrow crevice, used for splitting, tightening, securing, or levering.<br />3/4/2010<br />math<br />10<br />
11. e.Q 3:what is the state of matter?<br />State of matter have 3 parts which is solid liquid and gas.<br />3/4/2010<br />math<br />11<br />
12. gas<br />The state of matter distinguished from the solid and liquid states by relatively low density and viscosity, relatively great expansion and contraction with changes in pressure and temperature, the ability to diffuse readily, and the spontaneous tendency to become distributed uniformly throughout any container.<br />3/4/2010<br />math<br />12<br />
13. solid<br />Of definite shape and volume; not liquid or gaseous<br />3/4/2010<br />math<br />13<br />
14. liquid<br />The state of matter in which a substance exhibits a characteristic readiness to flow, little or no tendency to disperse, and relatively high incompressibility.<br />3/4/2010<br />math<br />14<br />
15. Picture of a liquid<br />3/4/2010<br />math<br />15<br />
16. Picture of a solid<br />3/4/2010<br />math<br />16<br />
17. Picture of a gas<br />3/4/2010<br />math<br />17<br />
18. questions<br />Do you learn any thing I taught you?<br />Your answer:<br />3/4/2010<br />math<br />18<br />
19. question<br />Do you know formula for speed ?<br />Distance over time or miles per hour?<br />3/4/2010<br />math<br />19<br />
20. end<br />Thanks for listening and learning<br />3/4/2010<br />math<br />20<br />
