Question

1. Looking at graph #, is the slope increasing decreasing or constant? What is the meaning of the slope? What is the acceleration?

2. Looking at the middle part of the graph #2, what can you say about the slope? How much is the velocity and acceleration?

3. Looking at the end part of graph #2, what can you say about the slope? How much is the velocity and acceleration?

4. How do you find the slope on a graph? What are the units of the slope?

You make a plot of distance vs. time as shown in the figure below:

1.for graph 2,slope is constant for first part,slope is zero for second part and slope is constant for third part.

it means acceleration is zero.

2.for the middle part,slope=0

so position does not change with time.

so velocity=0

acceleration=0

3.slope is -ve.

so velocity is -ve.

acceleration is 0.

4.to find slope,

take any two points in the vicinity of each other,

then use the formula

(y-coordinate of second-t y coordinate of first) / (x coordinate of second-x coordinate of first)
