Answer 2

Hey dear,

◆ Position-time graph -

• It represents the change in position of the particle w.r.t. time.
• Velocity of the particle is is calculated by slope of the position-time graph.

(I) For a particle at rest -

• Position-time graph of particle at rest is a straight line parallel to x-axis.
• Slope of this graph is zero, thus velocity = zero.

(II) For a particle moving with constant velocity -

• Position-time graph of particle moving with constant velocity is an ascending straight line.
• Slope of this graph is fixed, thus velocity = constant.

Hope this helped you. Thanks for asking..
