Write definition of instantaneous velocity.

Option A

Option B

Option C

Option D

Solution

The average velocity tells us how fast an object has been moving over a given time interval but does not tell us how fast it moves at different instants of time during that interval. For this, we define instantaneous velocity.

Physics

A particle moves along $X-$axis in such a way that its coordinate $X$ varies with time $t$ according to the equation $x = (2 – 5t + 6{t^2})\,m$. The initial velocity of the particle is…….$m/s$

Which of the following velocity-time graphs shows a realistic situation for a body in motion

easy

(AIIMS-2004)

The position of a particle along $x$-axis at time $t$ is given by $x=2+t-3 t^2$. The displacement and the distance travelled in the interval $t=0$ to $t=1$ are respectively

The displacement of a particle starting from rest (at $t = 0$) is given by $s = 6{t^2} – {t^3}$. The time in seconds at which the particle will attain zero velocity again, is ….. $\sec$

easy

A particle is moving in a straight line. The variation of position $x$ as a function of time $t$ is given as $x=\left(t^3-6 t^2+20 t+15\right) m$. The velocity of the body when its acceleration becomes zero is ……….. $m/s$
