Mastering Distance-Time Graphs and Speed Calculation

The video tutorial explains how to plot a distance-time graph, starting with drawing axes and plotting variables. It covers choosing an appropriate scale, plotting data points, and drawing a best-fit line. The tutorial concludes with calculating the slope of the graph to determine speed, the key physical quantity derived from a distance-time graph.

What is the point called where the x-axis and y-axis intersect?

• Base

• Intersection

• Origin

• Vertex

On which axis should time be plotted in a distance-time graph?

• y-axis

• z-axis

• x-axis

• w-axis

What should you do to ensure the data is well spread out on the graph paper?

• Use a small scale

• Choose a proper scale

• Plot all points at the origin

• Use only the x-axis

How should points be marked on the graph?

• With stars

• With triangles

• With squares

• With crosses or dots encircled

What geometric shape is used to find the slope of the graph?

• Rectangle

• Right-angled triangle

• Square

• Circle

What physical quantity is determined by the slope of a distance-time graph?

• Acceleration

• Speed

• Velocity

• Distance
