Question

Can Anyone explain me this phrase :the Gradient of the tangent at a point on the distance time graph gives us the instantaneous speed

Answer 1

instantaneous velocity=\[\lim_{\Delta t \rightarrow 0} \Delta x/\Delta t\]
let me draw a graph

Answer 2

x - displacement , \[\Delta x\] -change in displacement
t-time, \(\Delta t\)- change in time

Answer 3

k Mate thanks for helping

Answer 4

at time t1 the particle is at x1 and at t2 the particle is at x2
