Distance and velocity vs. The data table — distance, velocity vs. Excel : create the distance and velocity vs. If the object's speed is increasing at a fixed rate it is uniformly accelerated motion. The interesting relationship here is between distance and time. The distance depends on both the time and speed.
Since the speed is also proportional to the time,. So, in the case of constant acceleration, the distance is proportional to the square of the time. The general equation when the acceleration equals a constant acceleration is. The object moves by uniformly accelerated motion if a constant force acts upon it. The greater force produces the greater acceleration. When the same force acts upon different masses, the greater mass receives the smaller acceleration.
Formula of law is. S tudents compare these two values and explain the differences. Related experiments. Tim Montgomery and his world record in Which car has the best acceleration? Is it possible to measure the free-fall acceleration using the plexiglass strip? Experimental data Calibrated e-Prolab file Example of distance and velocity vs. Since the speed is also proportional to the time, the distance depends on the square of the time. Solving equation 1 for t 2 - t 1 and substituting the value into equation 4 :.
Experimental error can be calculated as follows:. The experimental setup is composed of the following:. The velocity of the object, moving on a horizontal plane, is to be measured in the first part of the experiment. In order to do this, the ideally frictionless metal track is placed on the table straightly, so that there is no slope between the table and the track.
Then the two photogates are arranged, initially overhanging 20 cm apart as shown in figure 1. Figure 1 Arrangement of the Photogates. Next, the picket fence is to be placed on the cart and it is checked whether the photogates are analyzing the cart or not by pushing it on the track. After plugging the wires of the photogates into the digital channels 1 and 2, which are on the digital panel of the signal interface as shown in figure 2.
And the interface is turned on by means of the switch at its back. Figure 2 Wire Connections to the Signal Interface. Doing these, the small cart is established on the metal track thus the setup became ready for taking data. Finally, it is checked whether there are 12 data points or not. Data obtained during Run 1 are tabulated in table 1. Run 1. Table 1. Sample Calculations for Run 1 are as follows:.
Data obtained during the experiment is tabulated in Table 2. Table 2. The cart is expected to reach a constant velocity and then continue moving at the same speed along the same direction from then on. The average velocity of the cart is will be equal to the instant velocity and the acceleration will be zero since there is no force acting on the cart during its motion on the ideal frictionless track.
In fact there exists friction between cart and the track. As a result, the motion does not happen as expected. The velocity of the cart decreases after being pushed since friction acts negatively on the cart. Do you expect that they will be equal? As we know, v ave a can be equal to average velocity only if acceleration is constant during the motion because the area under graph of velocity in velocity and time graph of inconstant accelerating motion is not equal to the area under graph of velocity in the velocity and time graph of constant accelerating motion.
Comment on possible results.
The percent error for this experimental value of freefall acceleration versus the actual is represented below. Acceleration is directly related to the angle of an incline. Reasons for the mild percent error are issues of rounding numbers and slight inaccurate selection of graph segments when collecting data for linear and quadratic acceleration.
