<p>This work sheet is to practice calculations using the <em>F=ma</em> formula.<br /> It gives 3 questions, each of which calculate 1 of <em>F</em>, <em>m</em> or <em>a</em> 3 times each.<br /> The wording changes the order in which the data is described eg for calculating <em>F</em>, one question gives <em>a</em> first then <em>m</em>, a second question gives <em>m</em> first etc.<br /> 1 in 3 questions uses <em>grams</em> instead of <em>kg</em>, so requiring a conversion calculation.<br /> 10 (numerically different) versions of each question are given - so the questions could be used as homework or revision and then the same questions, with different numbers, could be used in a classwork or test.<br /> Or, different versions could be handed out to different pupils if there was danger of copying of answers.<br /> Or both, given there are 10 versions.<br /> Each set has an ID number to easily find the correct answers for each version.<br /> All answers are given to 3 sf.</p>
