I will keep adding captions throughout today (11/17):
-
- PhyFl18-SS2.6.1 A new record? I can’t see that small to count. We have one more of these Astronomy talks. You all have impressed them so much that now they want to do more talks about all kinds of science subjects. Also, the Biology Department wants you to come to their lectures. You have power in your numbers. Everyone at OU wants a piece of the NHS Physics crowd.
-
- PhyFl18-SS2.6.2 this is left over from Test 2A, but it was the most missed problem. secant slopes make the steps and tangent slopes make the dots in the middle each step.
-
- PhyFl18-SS2.6.3 It is where the famous equation for average velocity comes from. the v bar is the slope of the secant line, the Vo is the slope of the tangent line at the beginning of the segment and the Vf is the slope of the tangent line at the end of the segment. This only works for Trios.
-
- PhyFl18-SS2.6.4 Here is a few more graphs of a bullet in a barrel. Notice how the acceleration is front loaded because explosions are P-waves (pulse or pressure) Sometimes called a concussion wave. This also shows the rifling (spiraling) of the bullet.
-
- PhyFl18-SS2.6.5 The blue rectangular area from the AVERAGE acceleration is the same as the the area under the actual instantaneous acceleration. Both, in this case, are 600m/s
-
- PhyFl18-SS2.6.6 Is this a Crackle? (a sextet) or maybe even a pop (septet) We would have to break down the function of the front loaded mountain to find out.
-
- PhyFl18-SS2.6.7 Okay, so here is one like THT2B.18. Even though we know it is just the AVERAGE acceleration we can use that area to determine the velocity of the bullet as it moves through the barrel and we can even determine the length of the barrel. It is simply a matter of finding the areas of the lower graphs to determine the function of the graph above. This is the basis of integral calculus.
-
- PhyFl18-SS2.6.8 Another example
-
- PhyFl18-SS2.6.9 this one is similar to the take home test 2B
-
- PhyFl18-SS2.6.10 you should try it yourself. try to go from an a vs. t graph to a v vs. t graph and then to a x vs. t graph.
-
- PhyFl18-SS2.6.11 Here is a tough problem. I would look it over REALLY good before the test Monday.
