<pre class=\\\"answer-content\\\">On the experimental results α = k m / F mathematical proof
High school physics an important part of teaching, the teaching process is generally as follows: first experiment: When m to maintain a certain time. By mouth F; when F remain constant, by mouth m ~. Then obtained by the two experimental relationship nF ? m ~. However, students often have to make the following question: Multiply the above two experimental results, not to be F ? m-1 yet? Teachers from the front, this is difficult to answer, had said from the negative side: Only recognition of nF ? m ~, to Two experiments included the conclusion that to maintain a certain time when the m, mouth F; when F remain constant, by mouth m ~. Although the students being able to How to make high school students on this issue from the front to accept _ the mathematical argument it? This paper makes a preliminary study for reference. By the experimental know: when the mass m is constant, so = kl (m). (1) r when the force is constant, a. rn = 2 (F). (2) changes due to curse, m will change with, so k. (M) is the only function on the m. Because the muscle changes, F must change with, so 2 (F) is just about the F function. Now any fixed variable m, first as a set of experimental data obtained (F., Mouth I,tory burch reva, m), into (1), (2) was t =, mouth Im = k2 (FI). (3) (4) of the obtained solution: (. (5) and then either take a set of experimental data (F2, n2, / lt1.), Empathy may have: F2 = m ?。().( 6) from (5 ), (6) can be obtained.:: m, (. (7) a hundred million m. Ju So, when the mass m, is constant,ugg botas, no matter what the value of the total force: (. (setting) take F = l, are: J, l, (/ lt1.t): 1), (set (8) and then fixed variable m,uggs kopen, the same way you can prove that:: m-.m I): 1). (setting) (9) from (8), (9), we have,tory burch outlet, no matter what value m, constant there:: m (: flail): 1) \\\'is 2 (F) = 2 (1) ? F. (10) [or kt (m) = mI (1)] to (10) into (2) be: muscle = k2 (1) ? F, take the international system of units known: k2 (1) = 1,uggs outlet rotterdam, \\\' So mouth: F / m. Physics in high school there as I = U / I {other law derived, a similar approach can also be demonstrated.
