WebAug 28, 2004 · 11. Gonzolo said: The short answer is that light doesn't have a rest mass. Only relativistic mass. And it is affected by gravity because gravity curves space-time. Gravity curves spacetime near a ray of light becouse light has momentum and energy, and those gravitate, along with the mass the light doesn't have. WebMar 6, 2024 · The acceleration due to gravity does not depend on the mass of the object falling, but the force it feels, and thus the object’s weight, does. This tells us two things. One is that the speed at which an object falls does not depend on its mass. Why does mass affect acceleration?

WebConsider an object of mass m m m m being lifted through a height h h h h against the force of gravity as shown below. The object is lifted vertically by a pulley and rope, so the force due to lifting the box and the force due to gravity, F g F_g F g F, start subscript, g, end subscript, are parallel. WebMar 26, 2016 · g = 9.8 meters/second 2 = 32.2 feet/second 2. Acceleration is a vector, meaning it has a direction and a magnitude, so this equation really boils down to g, an acceleration straight down toward the center of the Earth. The fact that F gravity = mg is important because it says that the acceleration of a falling body doesn’t depend on its … cipralex intoxikation

WebJun 23, 2024 · Mathematically, we say the force of gravity depends directly upon the masses of the objects and inversely upon the distance between the objects squared. Why is gravity dependent on mass? According to theory, the reason mass is proportional to gravity is because everything with mass emits tiny particles called gravitons. WebAug 25, 2024 · Gravity is the attractive pull between two objects that have mass. The strength of gravity is directly proportional to the amount of mass of each object. In other words, the larger the...
