Venn diagrams are used for comparing and contrasting topics. the overlapping sections show characteristics that the topics have in common, and the sections that are unique to each topic show the characteristics that apply to only that topic. this venn diagram is comparing longitudinal waves and transverse waves.
“parallel” and “perpendicular” are switched.
the slinky descriptions of motion are switched.
particles travel along the wave in longitudinal waves.
particles move long distances in transverse waves.

Mass (kg) force (n) 5 25 10 50 15 75 20 100 a student was trying to find the relationship between mass and force. he placed four different masses on a table and pulled them using a spring scale. the table shows the different masses used in the experiment and the force required to pull each mass. the student concluded that more force was required to pull heavier objects. what comment would you make regarding his conclusion? a) no clear relation can be observed between mass and force from the data. b) there is a direct proportion between the mass and force listed in the table. c) gravity should have been taken into account while performing the experiment. d) there is an inverse proportion between the mass and force listed in the table.
