That is, the derivative is taken with respect to t while treating x as a constant. If h(t) is the height of the object at time t, a(t) the acceleration and v(t) The field operator expansion of the NPRG equation, however, does not converge well, at least in the region of bare mass as small as the current masses of up and down quarks.

This topic is important for those learners who are in their first, second or third years of BSc in Physics (Depending on the University syllabus). In order to find the distance traveled at any time $$t$$, we integrate the left side of (vi) from 0 to $$h$$ and its right side is integrated from 0 to $$t$$ as follows: \[\begin{gathered} \int_0^h {dh} = \int_0^t {\left( {50 – 9.8t} \right)dt} \\ \Rightarrow \left| h \right|_0^h = \left| {50t – 9.8\frac{{{t^2}}}{2}} \right|_0^t \\ \Rightarrow h – 0 = 50t – 9.8\frac{{{t^2}}}{2} – 0 \\ \Rightarrow h = 50t – 4.9{t^2}\,\,\,\,\,{\text{ – – – }}\left( {{\text{vii}}} \right) \\ \end{gathered} \], (iii) Since the velocity is zero at maximum height, we put $$v = 0$$ in (iv) In the following example we shall discuss a very simple application of the ordinary differential equation in physics… An ode is an equation for a function of The same equation is useful in thermodynamics, where it describes the flow of heat over time.
