Forces Glossary

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.

The size of a vector quantity.

The amount of matter in an object and a measure of its inertia.

the product of an object's mass and its velocity. Mathematically, it can be expressed as p = mv, where m is the mass of the object, and v is its velocity.

The change in momentum of interacting objects caused by forces between them.
