What does the slope of time graph indicate?
A sloping line on a speed-time graph represents an acceleration. The sloping line shows that the speed of the object is changing. The object is either speeding up or slowing down. .
What does the slope mean on a graph?
The steepness of a hill is called a slope. The slope is defined as the ratio of the vertical change between two points, the rise, to the horizontal change between the same two points, the run. …
What is the significance of the slope?
The concept of slope is important in economics because it is used to measure the rate at which changes are taking place. Slope shows both steepness and direction. With positive slope the line moves upward when going from left to right. With negative slope the line moves down when going from left to right.
Can the run be negative?
That means left is the negative direction for run. A way to remember this is to think about the numbers are on the x-axis. Going to the right of the origin are the positive values, and going to the left of the origin are the negative values.
What is gentle slope?
A steep slope refers to a sharp incline; a gentle slope refers to a slight incline. The steep, forested slopes in Figure 1.1 contrast with the gentler slope of the river’s path as it flows between them.
What are the basic elements of slope?
Elements of slope A slope profile commonly consists of convex (crest),rectilinear and concave slope forms. Convex slopes are commonly found at the top and concave slopes lie at the base of the hillslope.
What is a free face of a slope?
The free face is a steep scarp/cliff, usually composed of hard rock and not accumulated by debris. All material readily falls on the fall face hence the name.
What is a convex slope?
A terrain feature that is curved or rounded like the exterior of a sphere or circle, i.e. goes from less steep to more steep. Convex slopes generally tend to be less safe than concave slopes, but concave slopes can also avalanche.
What is the difference between concave and convex slope?
The concave slope is represented by the closely spaced contour in the upper locations and gradually become widely spaced in the lower areas. – Convex slope is a geographical feature with inconstant slopes. The convex slope is represented by the contour lines that have opposite features to the concave slope.
