The higher the modulus, the more stress is needed to create the same amount of strain; an idealized rigid body would have an infinite Young's modulus. Conversely, a very soft material (such as a fluid) would deform without force, and would have zero Young's modulus.
Young's modulus (or the Young modulus) is a mechanical property of solid materials that measures the tensile or compressive when the force is applied lengthwise. It is the for or axial . Young's modulus is.
Young's modulus, $${\displaystyle E}$$, quantifies the relationship between tensile or compressive $${\displaystyle \sigma }$$ (force per unit area) and axial
Young's modulus is calculated by dividing the , $${\displaystyle \sigma (\varepsilon )}$$, by the , $${\displaystyle \varepsilon }$$, in the elastic (initial, linear) portion of the physical :
Young's modulus enables the calculation of the change in the dimension of a bar made of an elastic material under tensile or compressive loads. For instance, it predicts how much a material sample extends under tension or shortens under compression. The Young's modulus.

As a unit of measurement, the solar mass came into use before the astronomical unit and the gravitational constant were precisely measured.
The solar mass (M☉) is a frequently used in , equal to approximately 2×10 . It is approximately equal to the mass of the . It is often used to indicate the masses of other , as well as
The value of the gravitational constant was first derived from measurements that were made by in 1798 with a . The value he obtained differs by only 1% from the.
The Sun is losing mass because of occurring within its core, leading to the emission of and neutrinos, and by the.
The mass of the Sun cannot be measured directly, and is instead calculated from other measurable factors, using the equation for the of a small body orbiting a central mass. Based on the length of the year, the distance from Earth to the Sun (an
One solar mass, M☉, can be converted to related units:• 27068510 M☾ ()• 332946 M🜨 ()• 1047.35.
