Question
Wired Faculty App

A particle is moving with constant velocity of 5m/s. What will be the slope of (a) position time graph (b) velocity time graph?

Answer

Given, a particle is moving with a constant velocity 5 m/s. 

(a) Slope of position-time graph will give us the speed of the particle. Speed will be equal to 5m/s.

(b) Slope of velocity-time graph will be zero because velocity is constant.
