Question

Sketch a velocity - time graph
for the motion of the body.
From the graph explaining each
step, calculate total distance
covered by the body.​

Answer 1

Answer: Here is your answer......

Explanation:

The variation in velocity with time for an

object moving in a straight line can be

represented by a velocity-time graph. In this

graph, time is represented along the x-axis and the velocity is represented along the

y-axis. If the object moves at uniform velocity,

the height of its velocity-time graph will not

change with time (Fig below). It will be a straight

line parallel to the x-axis. Fig below shows the

velocity-time graph for a car moving with

uniform velocity of 40 km/h.

We know that the product of velocity and

time give displacement of an object moving

with uniform velocity. The area enclosed by

velocity-time graph and the time axis will be

equal to the magnitude of the displacement.

To know the distance moved by car

between time t1 and t 2

using Fig below, draw

perpendiculars from the points corresponding

to the time t1  and t2 and t2 on the graph. The velocity

of 40 km h–1 is represented by the height AC

or BD and the time (t2 – t 1 ) is represented by

the length AB.

So, the distance s moved by car in

time (t2 – t1 )

can be expressed as

s = AC × CD

= [(40 km h–1) × (t 2 – t1) h]

= 40 (t 2 – t1) km

= area of the rectangle ABDC
