Graphical Representation of Motion

The speed-time graph for a car is shown in figure.

Which part of the graph represents the uniform motion of the car?

Figure shows the distance-time graph of three objects A, B and C. Study the graph and answer the following question:

How far has B travelled by the time it passes C?

Figure shows the distance-time graph of three objects A, B and C. Study the graph and answer the following question:

How far has C travelled when B passes A?

Figure shows the distance-time graph of three objects A, B and C. Study the graph and answer the following question:

What is the quantity which is measured by the area occupied below the velocity-time graph?

What can you say about the motion of an object if its speed-time graph is a straight line parallel to the time axis?

What can you say about the motion of an object whose distance-time graph is a straight line parallel to the time axis?

What is the nature of the distance-time graphs for uniform and non-uniform motion of an object?

A train starting from a railway station and moving with uniform acceleration attains a speed $40 \mathrm{k}\mathrm{m}/\mathrm{h}$ in $10 \mathrm{minutes}$. Find its acceleration.

The speed-time graph for a car is shown in figure.

Find how far the car travels in the first $4 \mathrm{seconds}$. Shade, the area on the graph that represents the distance, travelled by car during the period.

Figure shows the distance-time graph of three objects A, B and C. Study the graph and answer the following question:

Which of the three is travelling the fastest?

A driver of a car traveling at $52 \mathrm{k}\mathrm{m}/\mathrm{h}$ applies the brakes and accelerates uniformly in the opposite direction.The car stops in $5 \mathrm{s}.$ Another driver going at $3 \mathrm{k}\mathrm{m}/\mathrm{h}$ in another car applies his brakes slowly and stops in $10 \mathrm{s}.$ On the same graph paper, plot the speed versus time graphs for the two cars. Which of the two cars travelled farther after the brakes were applied?
