a) Equation for velocity-time graph→
From the above graph,
Acceleration (a)= Slope of the graph
a= AB
a=BC/AC [*Slope of graph=Y-Axis/X-Axis]
a=v-u/t
a*t=v-u
at=v-u
at+u=v
v=at+u
v=u+at
Hence, Derived
b) Odometer
c) Yes, it may be zero for some special cases when the initial and the final position of the object remains the same for example- When an athlete runs a 400m race his initial position and final position remains the same.
