3. compare the slope of the velocity-time graph to the average of all your acceleration values. are they close? what does the slope of a velocity (or speed) vs. time graph mean? explain the answer using your data. how does the value of g that you calculated compare to the accepted value of 9.80 m/s2? what is your percent error? remember that the value of g can be calculated by using g = a/sinθ and percent error can be calculated using the following equation:

Which best describes the difference between internal and thermal energy?

Which of the following forces require physical contact? tension air resistance friction magnetic force applied force

Ascientist is working with a new kind of quantum dot to make a dye. he is applying newton’s laws to the particle, but it seems to be breaking these laws of physics. which action will most likely the scientist study the particle’s motion? a. he needs to remember that the particle is too large for quantum analysis. b. he must continue to use newtonian mechanics, but he needs to learn more about the particle. c. he needs to use quantum mechanics, not newtonian mechanics, because this is a nanotechnology product. d. he must determine new physical laws that only apply to quantum dots.
