science class the week of 3- 30

in class this week we started to talk about dynamics and the frces that the earth has on an object. and in return, the force that the object put on things around it or back on the earth. we also talked about newtons. newtons are how you measure the force the earth has on an object. we conducted an experiment that showed us the basics of the newtons, (n). we used a spring scale, which is a tube with a spring inside and when an object is attached to the hook on the bottom, the slide goes down and you can find the reading of n. also there is a scale that is like a spring scale but has a digital display. this scale played the same role as the spring.
