Change in velocity

Vedclass · Answer

(D) The correct option is $D$.By definition,acceleration $a$ is the rate of change of velocity with respect to time,given by the formula $a = \frac{dv}{dt}$.Rearranging this equation,we get $dv = a \cdot dt$.To find the total change in velocity over a time interval from $t_1$ to $t_2$,we integrate both sides: $\Delta v = \int_{t_1}^{t_2} a \cdot dt$.Geometrically,the integral $\int a \cdot dt$ represents the area under the acceleration-time graph.Therefore,the area under the acceleration-time graph gives the change in velocity of the object.

The area under an acceleration-time graph gives:

How can instantaneous velocity be found by the graphical method?

The position of an object moving along the $x$-axis is given by $x = a + b t^{2}$,where $a = 8.5 \; m$,$b = 2.5 \; m s^{-2}$,and $t$ is measured in seconds. What is the velocity at $t = 0 \; s$ and $t = 2.0 \; s$?

Draw the $x-t$ graphs which represent positive,negative,and zero velocity.

The $v-t$ graph of a rectilinear motion is shown in the adjoining figure. The distance from the starting point after $8 \text{ s}$ is .......... $\text{m}$.

An object at rest at the origin begins to move in the $+x$-direction with a uniform acceleration of $1 \, m/s^2$ for $4 \, s$ and then it continues moving with a uniform velocity of $4 \, m/s$ in the same direction. The $x-t$ graph for the object's motion will be:
