An object falls freely from rest in a vacuum. The graph shows the variation with time t of the
velocity $$v$$ of the object.
Which graph, using the same scales, represents the object falling in air?

Question

An object falls freely from rest in a vacuum- The graph shows the variation with time t of thevelocity v of the object-Which graph- using the same scales- represents the object falling in air-

Toppr Admin · Accepted Answer

Correct option is A- In free fall in air- the only force acting on object is gravity-160-dfrac-dv-dt- g-Since -g- is constant-160-implies -dfrac-dv-dt- -constantThis implies that slop of -v-t- graph is constant-So- option A is correct-160-

An object falls freely from rest in a vacuum. The graph shows the variation with time t of thevelocity $$v$$ of the object.Which graph, using the same scales, represents the object falling in air?

Correct option is A. In free fall in air, the only force acting on object is gravity. $$\dfrac{dv}{dt}= g$$Since $$g$$ is constant. $$\implies \dfrac{dv}{dt}= $$constantThis implies that slop of $$v-t$$ graph is constant.So, option A is correct.

Correct option is A.
In free fall in air, the only force acting on object is gravity.
$$\dfrac{dv}{dt}= g$$
Since $$g$$ is constant.
$$\implies \dfrac{dv}{dt}= $$constant
This implies that slop of $$v-t$$ graph is constant.
So, option A is correct.
