Since the ball is moving in a positive direction its velocity is positive. This represents the balls average velocity as it moves across the table. The slope of this line would equal 20 cm divided by 0.1 sec or 200 cm/sec. In our constant velocity lab we used the motion sensor to measure the position of an object 100 times a second and plotted the data as a graph of position vs. In the two fuel stages, the rocket experiences an upward acceleration of 10 m/s/s and 4.29 m/s/s respectively. Lets assume this distance equals 20 cm and display the balls behavior on a graph plotting its x-position versus time. We say that linear increasing in position is the result of constant velocity. Red line shows nonlinear increasing and black line shows linear increasing. This position time graph is an example of increasing position in negative direction. Acceleration as a function of time graphs. We will solve more examples using graph for deep understanding and analyzing the motion from the graphs. The rocket has two consecutive fuel stages followed by a free-fall motion (no fuel). In the previous example we solved parts (a) and (b) and now we are going to draw the Position, Velocity and. Graph the position velocity and acceleration of a ball released from rest. Slope = 3 m − 1 m 4 s − 0 s (Pick two points and plug the x values into the numerator and the t values into the denominator.) \text distance = 9 m start text, d, i, s, t, a, n, c, e, end text, equals, 9, start text, space, m, end text. Observe the motion of the two-stage rocket and the corresponding velocity-time graph below. Typically the first problem in a series of worked examples pertaining to freefall.
