# what is instantaneous velocity on a position time graph

4. Draw position - time graph for motion with (a) positive acceleration (b) negative. acceleration (c) zero acceleration.When instantaneous velocities of a particle in motion are plotted against time, the resultant graph is called velocity - time graph. v. u. The graph is a curve at this point and a tangent should be drawn on the graph in order to calculate an instantaneous gradient. (b) On the axes below sketch a velocity-time graph for the car over. the same period of time. Let s (t) be the position of an object at time t. The instantaneous velocity at t a is defined as .Note that this graph is not a drawing of the path of the object, but is a graph of height versus time. The object was actually tossed straight up and fell straight back down. Above position time graph represents an object at rest at position x1, in positive direction.Position Time graphs are also called x t graphs.

Slope of Position Time graph gives instantaneous velocity. In linear motion, the instantaneous velocity vx at any particular time is given by the gradient of the tangent to the positiontime graph at that time, i.e.A2 Plot positiontime, displacementtime and velocitytime graphs from linear motion data. The graph was not a straight line. The definition of instantaneous velocity.At any one instant, he argued, there is no change of time, no change of position, which means: no motion. -1. Displacement on a turn with constant speed with a pitfall. 0. Obtaining position from a curved velocity vs time graph. 0.What is initial velocity here? -1. For how long is an objects velocity its instantaneous velocity at time t? Instantaneous Velocity - The velocity at an instant in time. If the velocity is not constant, then the slope of the position time graph is not constant and therefore velocity changes. Family Davila: when is the instantaneous velocity the greatest on a graph? Galaco Aoi: Thank you soo much this was really helpful.
