shiyan(十堰) shiyan(十堰) Measure 113 Using vernier calipers and spiral micrometer, master the principle and method of measuring length. 114. Study the uniform speed linear motion The right picture is a paper strip for a dot timer. Setpoint tracking and clear one, began to lay down more dense point, from the place of measurement purposes O A start point, then the interval (every five points) A count points A, B, C, D... It is. The distance between the adjacent counting points is measured, s1, s2, s3... Using a shot tape can: The instant speed v for any counting point is asked for: for example (T = 5 * 0.02 s = 0.1 s) The essay seeks a: Using the two adjacent displacement in the figure above, a: for example I use v-t image to solve for a: to find the instantaneous velocity of each point of a, B, C, D, E, and F, and to draw the v-t line of the right, the slope of the graph line is acceleration a. Note number 1, a count point is taken at intervals of 5 intervals to facilitate calculation for acceleration. 2. The counting points are guaranteed to have at least two valid digits 115. Inquiry
