Thursday, April 9, 2015• Do Now: Greg is interested in
building a rocket that will fly vertically the greatest distance. After research, he determines that the fins of the rocket have the greatest affect on altitude, but is unsure what shape is best. Identify the following elements of a proposed science experiment he could design to answer his question:–Question–Variables–Type of Graph?
Today’s Goals:• Forces and Motion Review BINGO!
•We will stop occasionally to elaborate/expand/practice and discuss
•Winner (s) get a prize!

Law of motion: there is a relationship between force, mass and acceleration; F=ma; the amount of force required to move an object increases as the
mass of the object increases; the acceleration of an object decreases as its mass increases
Law of motion: an object in motion, stays in motion and an object at rest stays at rest, UNLESS acted upon by an outside force
The force of attraction between objects; pulls them together; increases as distance decreases; increases as mass increases
