This analysis of the slope on the graph is consistent with the motion of a free-falling object - an object moving with a constant acceleration of 9.8 m/s/s in the downward direction. To prepare for this lab you will want to review position vs. Observe that the line on the graph is a straight, diagonal line. A velocity versus time graph for a free-falling object is shown below.

Since the slope of any velocity versus time graph is the acceleration of the object ( as learned in Lesson 4), the constant, negative slope indicates a constant, negative acceleration. Representing Free Fall by Velocity-Time Graphs. An object that is moving in the negative direction and speeding up is said to have a negative acceleration (if necessary, review the vector nature of acceleration). In the present paper, we describe simple experiments that allow one to demonstrate the conservation of energy where the initial gravitational potential energy. A further look at the velocity-time graph reveals that the object starts with a zero velocity (as read from the graph) and finishes with a large, negative velocity that is, the object is moving in the negative direction and speeding up. Since a free-falling object is undergoing an acceleration (g = 9,8 m/s/s, downward), it would be expected that its velocity-time graph would be diagonal. Does the initial velocity of an object have anything to. As learned earlier, a diagonal line on a velocity versus time graph signifies an accelerated motion. Motion graphs of vertical fall against air-drag - PhysicsTeacher.in WebDraw the position - time, velocity - time and acceleration - time graphs for a freely. If an object is moving with constant acceleration, what is the shape of its velocity vs.
