6. a position time graph of an object is shown below.
a what is the total distance the object traveled?
b. what is the displacement of the object between 2s and 4s?
c. is the velocity positive or negative?
postin (motor)
d. is the velocity increasing, decreasing or constant?
e. what is the average velocity of the object between 2 & 45?
f. calculate the instantaneous velocity of the object at 1.5s.
time (seconds)
a lot of points!

Mike walks 100 meter north, then walks 30 meters south. after this, he walks another 10 meters north. what is the magnitude of his total displacement during this walk,in meters?

First, launch the video below. you will be asked to use your knowledge of physics to predict the outcome of an experiment. then, close the video window and answer the question at right. you can watch the video again at any point. part a as in the video, we apply a charge +q to the half-shell that carries the electroscope. this time, we also apply a charge –q to the other half-shell. when we bring the two halves together, we observe that the electroscope discharges, just as in the video. what does the electroscope needle do when you separate the two half-shells again? view available hint(s) as in the video, we apply a charge + to the half-shell that carries the electroscope. this time, we also apply a charge – to the other half-shell. when we bring the two halves together, we observe that the electroscope discharges, just as in the video. what does the electroscope needle do when you separate the two half-shells again? it deflects more than it did at the end of the video. it deflects the same amount as at end of the video. it does not deflect at all. it deflects less than it did at the end of the video. submit

Why is the energy that results from a roller coaster's position at the top of a hill referred to as potential energy?
