If your measuring something that can have any value in a range what should you do ?

And why should you use a line graph?

For example? ( the line graph)
Mass and spring extension could both be shown on a line graph.

Thermal Energy Notes
Everything has some energy in its thermal energy store- the hotter it is, the higher its temperature and the more energy it has in its thermal energy store.
WHY DO WE NEED TO LEARN PHYSICS!?
PHYSICS HELPS US TO UNDERSTAND HOW THE WORLD WORKS, from can openers, light bulbs and cell phones to muscles, lungs and brains; from paints, piccolos and pirouettes to cameras, cars and cathedrals; from earthquakes, tsunamis and hurricanes to quarks, DNA and black holes.
