A nutrient required by the body in relatively large amounts.

the equation for the force experienced by a charged particle moving in a field:

F = q(v x B)

In this equation, F represents the force, q is the charge of the particle, v is its velocity, and B is the field vector. The "x" symbol denotes the cross product between the velocity and field vectors.

A non-contact force between magnets or magnetic materials.

How many times larger an image appears compared with the actual object.

The size of a scalar or vector quantity.

A force on a spinning object moving through a fluid.
