Spring Thruster Build and calibrate a spring thruster for comparing forces and pushing. Use the thruster to study the effects of push on the motion of a puck. Reporting A record of your messing around in mechanics might include a short written description of each motion measurement. Diagrams are also helpful for explanation. Whenever measurements are made this data must be recorded carefully and accurately, with units included for clarity.
Tables are useful for repeated similar measurements.
To make the logic of your calculations clear, first record the formula you used, then show the numbers used to evaluate the formula, and finally record your answer. The result of the calculation is therefore a rough approximation. Reporting measurements to three significant digits of accuracy gives a much more useful result. To measure changing speed, multiple measurements must be made. In this case, a table is helpful for keeping order.
