Figure 1 When the switch is opened a timer starts and a steel ball is released from rest. The ball falls vertically onto an impact switch and this stops the timer. The timer displays the time t for the ball to fall through the vertical distance s shown in Figure 1. Question 1 continues on the next page box Turn over ► box . The student has used an absolute uncertainty in s to draw the vertical error bars in Figure 2. Deduce the student’s absolute uncertainty in s. box [1 mark] absolute uncertainty in s = m . Determine • the maximum gradient Gmax of a straight line that passes through all the error bars • the minimum gradient Gmin of a straight line that passes through all the error bars. [3 marks] Gmax = Gmin = Question 1 continues on the next page [Show More]
