The position of a body moving along the $x$-axis at time $t$ is given by $x = (t^2 - 4t + 6) \, m$. The distance travelled by the body in the time interval $t = 0$ to $t = 3 \, s$ is ...... $m$.

$A$ car moves with a speed of $60 \, km/h$ for $1 \, h$ in the east direction and with the same speed for $30 \, min$ in the south direction. The displacement of the car from the initial position is ......... $km$.

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

Your friend driving his car overtakes your car on the highway. Which of the following statements must be true at the instant he is passing you? Assume the cars as point particles.

What is a particle? How can we consider an object as a particle?

An airplane flies $400 \,m$ north and $300 \,m$ south and flies $1200 \,m$ upwards,then the net displacement is (in $\,m$)
