In thermodynamics, an isentropic process is an idealized thermodynamic process that is adiabatic and in which the work transfers of the system are ... more

In solid mechanics, torsion is the twisting of an object due to an applied torque. The torsion constant is a geometrical property of a bar’s ... more

The density, or more precisely, the volumetric mass density, of a substance is its mass per unit volume. The density of gases is strongly affected by ... more

Osmotic pressure is the pressure which needs to be applied to a solution to prevent the inward flow of water across a semipermeable membrane. The osmotic ... more

The concentration of a substance at time “t”, of a first-order reaction, depends only on the initial concentration and the properties of the ... more

Potential function for electrostatic forces between two bodies is the work required to move a charge from a point to any point in the electrostatic force ... more

Within a uniform spherical body of radius R and density ρ the gravitational force g inside the sphere varies linearly with distance r from the center, ... more

Every point mass in the universe attracts every other point mass with a force that is directly proportional to the product of their masses and inversely ... more

Generated at the center of a circular wire by the electric current, related to the electric current and the distance from the wire to center of the circle.

Specific internal energy is the internal energy per unit mass.
