Although the scientific method is a cyclic process, when investigating a problem for the first time, you must start somewhere. which of the following should be the first step in an investigation?
draw conclusions
collect data
define the problem
analyze the data

Consider two less-than-desirable options. in the first you are driving 30 mph and crash head-on into an identical car also going 30 mph. in the second option you are driving 30 mph and crash head-on into a stationary brick wall. in neither case does your car bounce off the thing it hits, and the collision time is the same in both cases. which of these two situations would result in the greatest impact force?
