Some physical applications of the Laplace transform Laila Ali Geraz, Eman Aleajili Daman College of Engineering Technology – Janzou Laila.gerazi@gmail.com, Eman.damann@gmail.com Abstract: In this paper, we present a study on the Laplace Transform in terms of: origin, definition, characteristics, and benefits. On the other hand, there is an inverse Laplace transform, which transforms functions from the range of complex variables to the dome variables, and one of the most important aspects of this transformation is that it gives specific solutions to possible functions, and therefore tables with potential solutions have been developed so that it can be referred to, and the Laplace transform is considered one of the most important integral transformations that has importance In solving some complex integrals, as well as some differential equations, where this transformation was used in some real-world applications, the most important of which are: the harmonic vibration of a flexible rod installed from, and the flow of current within an electric circuit, then we formulated w its terminals and loaded with a load the governing equations for these two applications, and the transformation was used to solve these equations. Keywords: Laplace transform, differential equations, Inverse Laplace transform, harmonic oscillation, electrical circuits
