Motion yay............

ok so this week in science we did a lot with graphs and motion diagrams. yes, motion diagrams. on monday we realized that dot diagrams were unreliable and they could display the wrong messgage. they could be going one way and not represent the right thing. so, we learned about motion diagrams. motion diagrams display velocity, direction, positive and negitives, adn more! how greattt.
on tuesday we leaned more about how to make a moition diagram and why they are better than dot diagrams.
okay so now on wednesday we drew motion diagrams for marbles rolkling down a hill. we also learned about path legth which is the distance that u travel. and we learned abuot displacemembt which corrisponds with velocity. on thursday and frieday we did wkrosheetyse
