Answer:

The area under a velocity-time graph is a representation of the displacement. If the area is over a time interval, then the displacement during that time interval can be measured by the area under the graph bounded by the time interval. ... Bonus: the slope of a V-t graph is a measure of acceleration.

Therefore the area under velocity – time curve represents the distance covered over a given time interval.

Given:

An object is moving with a constant velocity.

To Find:

The area under velocity – time curve represents the distance covered over a given time interval.

Solution:

The given question can be easily solved using the approach shown below.

We know the formula for velocity,

⇒ Velocity = ( Distance Travelled ) / ( Time Taken )

Then, Distance traveled = Velocity × Time Taken

A graph is plotted for Velocity on Y-axis and Time Taken on X-axis as shown in the figure attached.

The graph will be a horizontal line as the velocity is uniform.

So Area under the curve will be equal to the area of the rectangle.

On the Y-axis length of the rectangle = velocity V

On the X-axis length of the rectangle = Time interval  ( t₂ - t₁ ) = Time Taken T

So Area of the rectangle = Velocity × Time Taken

But from the formula of velocity, Velocity ×Time Taken = Distance traveled

Therefore the area under velocity – time curve represents the distance covered over a given time interval.
