The effective mass can be negative or different depending on the circumstances.

Under other circumstances, he would have been able to manage his effective mass; but not easily.

This is usually done by using the electrons' effective mass in place of m.

Double the effective mass of everyone aboard for forty- two minutes.

We can find the effective mass of the spring by finding its kinetic energy.

Typically the effective mass of electrons and holes are different.

In energy regions far away from a minimum, effective mass can be negative or even approach infinity.

Effective mass can be understood only with quantum mechanics.

The density-of-states effective masses are tabulated below for a few cases.

If the spring itself has mass, its effective mass must be included in .

This leads to the enhanced effective mass and a hybridization gap develops.

Effective mass, being generally dependent on direction (with respect to the Miller index), is a tensor.

So the effective mass of a spring is:

Effective masses can be derived from band structure computations.

In addition, strain rates data alone does not allow calculations of failure load, since neither direct force nor effective mass are typically reported.

In most semiconductors, the effective mass of a hole is much larger than that of an electron.

Relation between heat capacity and "thermal effective mass"

This hole was the size of a large planet, but it had the effective mass of a large star.

However, its mass can differ substantially from that of a normal electron; see the article effective mass.

Generally, in the absence of an electric or magnetic field, the concept of effective mass does not apply.

These parameters are very closely related to the effective masses of the holes in various valence bands.

So we introduce the concept of effective mass to describe the movement of an electron in Newton's law.

A lower carrier effective mass also favors increased tunneling current, a direct result of delocalization.

By the time the hole approached, Chiron's effective mass had reached about a tenth of the Sun's.

They could stand and watch from where they were, their bodies had no effective mass for gravity to operate on-vertical or otherwise.
