course phy 201 the bookstore has been out of lab kits and i have not yet been able to purchase it, on tuesday when they had them i was sold the wrong book and lab kit, so i do not have the book either right now. i have returned them and they are now out. on monday when the bookstore is open again i hope they will have both in stock for me.

09:34:18 What do we mean by velocity?
......!!!!!!!!...................................
RESPONSE --> rate position changes/change in time
.................................................
......!!!!!!!!...................................
09:34:59 How can we determine the velocity of a ball rolling down an incline?
......!!!!!!!!...................................
RESPONSE --> displacement/time interval to get the average velocity
.................................................
......!!!!!!!!...................................
09:36:26 We anticipate from our experience that a ball traveling down a greater incline, starting from rest, will experience a greater change in velocity. How can we determine whether the velocity actually changes, and whether the velocity increases in the manner that we expect?
......!!!!!!!!...................................
RESPONSE --> displacement/time interval to get an average velocity. Then try different inclines. The greater average is teh greater change in velocity
.................................................
......!!!!!!!!...................................
09:37:23 How could we determine the velocity of the ball at a specific point? The specific points are measured for distance and the ball is timed when it reaches these specific points. The distance is then divided by the time.
......!!!!!!!!...................................
RESPONSE --> take the slope of the tangent line on the graph position vs time interval
.................................................
......!!!!!!!!...................................
09:39:36 How do we determine the rate at which the velocity changes? How can we understand the concept of the rate at which velocity changes?
......!!!!!!!!...................................
RESPONSE --> divide the change in velocity by the time elapsed. ok.

09:47:34 It is essential to understand what a trapezoid on a v vs. t graph represents. Give the meaning of the rise and run between two points, and the meaning of the area of a trapezoid defined by a v vs. t graph.
......!!!!!!!!...................................
RESPONSE --> Rise over run is simply the slope of a line the change in velocity by the change in time.

09:48:01 What does the graph of position vs. clock time look like for constant-acceleration motion?
......!!!!!!!!...................................
RESPONSE --> a straight line
.................................................
......!!!!!!!!...................................
09:49:52 06-01-2006 09:49:52 How can we obtain a graph of velocity vs. clock time from a position vs. clock time graph?
......!!!!!!!!...................................
NOTES -------> ok
.......................................................!!!!!!!!...................................
09:49:53 How can we obtain a graph of velocity vs. clock time from a position vs. clock time graph?
......!!!!!!!!...................................
RESPONSE -->
.................................................
......!!!!!!!!...................................
09:59:47 How can we obtain a graph of position vs. clock time from a velocity vs. clock time graph
......!!!!!!!!...................................
RESPONSE --> taking the area of trapezoids in the graph. the area will show the change in position during time intervals
.................................................
......!!!!!!!!...................................
10:18:00 How can we obtain a graph of acceleration vs. clock time from a velocity vs. clock time graph?
......!!!!!!!!...................................
RESPONSE --> accelerarion is the change in velocity divided by time elapsed. we could find the average velocity and find the change in that?
.................................................
......!!!!!!!!...................................
10:22:27 How can we obtain a graph of velocity vs. clock time from an acceleration vs. clock time graph
......!!!!!!!!...................................
RESPONSE --> take the velocity points on the acceleration graph and plot these on a v vs t graph?

11:57:35 How does the shape of the corresponding position vs. clock time graph, with its upward curvature, show us that the time required to travel the first half of the incline is greater than that required to travel the second half?
