1 : a force of attraction that tends to draw particles or bodies together. 2 : the attraction of bodies by the force of gravity toward the center of the earth. 3 : great seriousness. What is gravity physics? Gravity is the force by which a planet or other body draws objects toward its center. … Read more

The vacuum flask was devised to preserve liquefied gases by preventing the transfer of heat from the surroundings to the liquid. The evacuated space between the walls (which are ordinarily glass or steel) is practically a nonconductor of heat; radiation is reduced to a minimum by silvering the glass or steel. How does a vacuum … Read more

Wave theory speculates that a light source emits light waves that spread in all directions. Upon impacting a mirror, the waves are reflected according to the arrival angles, but with each wave turned back to front to produce a reversed image (Figure 4). What are the main points of wave theory of light 12? Light … Read more

So far, the wave function has been interpreted as a probability amplitude, which is given physical meaning by ensemble averages of a large number of identical systems at a given time. We give an alternative interpretation of the wave function for a single system by means of a measurement which lasts a long time. What … Read more

A vector that has a magnitude of 1 is a unit vector. It is also known as Direction Vector. Learn vectors in detail here. For example, vector v = (1,3) is not a unit vector, because its magnitude is not equal to 1, i.e., |v| = √(12+32) ≠ 1. What are unit vectors in physics? … Read more

Velocity is defined as a vector measurement of the rate and direction of motion. Put simply, velocity is the speed at which something moves in one direction. The speed of a car traveling north on a major freeway and the speed a rocket launching into space can both be measured using velocity. What are the … Read more

A mechanical wave is an oscillation of matter that transfers energy through the matter. There are three types of mechanical waves: Transverse waves wherein the particles oscillate perpendicular to the direction that the wave travels. What are the mechanics of waves? Wave Mechanics. where A is the amplitude of the wave, k = 2p /l … Read more

Classical physics refers to physical ideas that actually predate newer, more comprehensive, or much more broadly applicable theories. Energy, as well as matter, have been regarded as independent concepts throughout classical physics. What are the types of classical physics? The traditional branches of classical physics are Optics, Acoustics, Electromagnetics, and Classical mechanics. What is classical … Read more

A sound wave is the pattern of disturbance caused by the movement of energy traveling through a medium (such as air, water or any other liquid or solid matter) as it propagates away from the source of the sound. Sound waves are created by object vibrations and produce pressure waves, for example, a ringing cellphone. … Read more

vector operations, Extension of the laws of elementary algebra to vectors. They include addition, subtraction, and three types of multiplication. The sum of two vectors is a third vector, represented as the diagonal of the parallelogram constructed with the two original vectors as sides. What are the 3 types of vectors in physics? Zero Vector. … Read more
