4 days ago · MEANING OF PHYSICS. Physics is the study of matter and its relation to energy. Matter is anything that occupies space and has weight. The study of physics allows one to understand and enjoy other subjects. As a subject, the study of physics involves measurement of quantities and collection of data.
4 days ago · Category. v. t. e. Mechanics of planar particle motion [1] is the analysis of the motion of particles gravitationally attracted to one another observed from non-inertial reference frames [2] [3] [4] and the generalisation of this problem to planetary motion. [5] This type of analysis is closely related to centrifugal force, two-body problem ...
5 days ago · The definition of $ {C_p}$ : The $ {C_p}$ is the amount of heat energy is released or absorbed by the unit mass of the substance with the constant pressure at change in temperature. In other words, in constant pressure the heat energy transfers between the system and its surroundings. The definition of $ {C_v}$ :
5 days ago · In the case of a freely falling body, it is the mechanical energy of the system that is conserved. Mechanical energy (E) is the sum of the potential energy (U) and the kinetic energy (K) of the freely falling body. Therefore, E=K+U=constant. Potential energy is defined as negative of the work done by the force affecting the body.
5 days ago · A phenomenon is observed when a body is subjected to external vibrations. If the frequency of the applied vibration is equal to the natural frequency of that body then the body starts vibrating with a very large amplitude. This phenomenon is known as resonance. The frequency at which resonance takes place is called resonant frequency.
2 days ago · For example, Albert Einstein's first paper on relativity begins by defining simultaneity and the means for determining length. These ideas were skipped over by Isaac Newton with, "I do not define time, space, place and motion, as being well known to all." Einstein's paper then demonstrates that they (viz., absolute time and length independent ...
4 days ago · In this explainer, we will learn how to apply derivatives to problems of motion in a straight line. The position of a particle in rectilinear motion can be described as a coordinate on the motion axis, 𝑥 ( 𝑡). It can also be expressed with respect to the particle’s position at a given time; this is called the displacement of the particle.
