Think of a topic of interest to you within the subject of earth and space science. how might the daily activities of a scientist studying that topic or field differ from a chemist, physicist, or biologist? how might it be the same? in what ways would the scientist likely use the scientific method? which types of data would they likely analyze most often?

the independent variable, the one that is intentionally manipulated, is whether or not the car hits the barrier.

the dependent variable, the one that you measure the response in, is the distance that the washers travel.

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )

the answer is b, have negligible mass

technology is the application of the knowledge gained by science.
