Non uniformly accelearted Motion ( Graphs)

Velocity- Time graph (Non-Uniform Acceleration) The velocity- time graph of non-uniformly accelerated motion is a curve. The slope of line joining between any two points on the v-t graph gives average acceleration. Average acceleration ( a_av)= (Change in velocity)/(time interval) = (v_2-v_1)/(t_2-t_1 ) = ∆v/∆t If an object is moving with non-uniform acceleration such that its acceleration is a1 in time t1 and a2 in time t2, then the average acceleration is given by a_av = (a_1 t_1+ a_2 t_2)/(t_1+ t_2 ) The slope of tangent drawn at any point of the v-t curve gives instantaneous acceleration corresponding to a particular time. Instantaneous acceleration (a) = lim┬(∆t →0)⁡〖∆v/∆t〗 = dv/dt Hence, the instantaneous acceleration is also defined as the slope of tangent to velocity – time graph corresponding to given instant of time. Acceleration-Time graph (a-t graph) The area under acceleration- time graph between time t1 and t2 gives the change in velocity. As, acceleration a = dv/dt dv = a.dt ∫On integration above equation we cna get change in velocity.
