Unformatted text preview: aken to be arbitrarily small. The actual proof the general case, requires calculus therefore we will not deal with the general case in this lab. When dealing with real-life situations, such as the experiment that you are about to do, the force on an object is rarely constant. For example, when a bat hits a baseball, the force increases very quickly, reaches some maximum value, and then decreases just as quickly. Figure 1 shows a typical graph of force verses time for such incidents. The force starts out small as the bat comes in contact with the ball, rises to a maximum value when they are firmly in contact, and then drops off as the ball leaves the bat. In order to analyze this rather complex interaction, it is useful to r define an average force Favg shown in Figure 2. 2 Figure 1: A force acting on an object may vary in time. The impulse is the area under the force vs. time curve. Figure 2: The average force (horizontal dashed line) gives the same impulse to the object in the time interval Δt as the real time-varying fo...
