The net force on the suspended body equals the sum of the tension in the string and the weight of the body. It is given by 𝐹 = (𝑚 𝑔) − 𝑇, where 𝑇 is the tension in the string and 𝑔 is the acceleration due to gravity.
21 godz. temu · In physics, the special theory of relativity, or special relativity for short, is a scientific theory of the relationship between space and time.In Albert Einstein's 1905 treatment, the theory is presented as being based on just two postulates:. The laws of physics are invariant (identical) in all inertial frames of reference (that is, frames of reference with no acceleration).
21 godz. temu · Hubble's law, also known as the Hubble–Lemaître law, is the observation in physical cosmology that galaxies are moving away from Earth at speeds proportional to their distance. In other words, the farther they are, the faster they are moving away from Earth. The velocity of the galaxies has been determined by their redshift, a shift of the light they emit toward the red end of the visible ...
