Magnetism is a natural force, one that works at a distance. Magnets get their force from magnetic fields created by the atoms within the metal. Magnets are useful for things like turbines we use ...

Gravity is the force of action between two objects. It’s called a natural force because it acts at a distance rather than needing to be in contact. Gravity is the force that holds us down on ...

This video is an introduction to shear force and bending moment diagrams. What are Shear Forces and Bending Moments? Shear forces and bending moments are resultants which are used to conveniently ...

Study the tiny molecular motors that cells use to produce force and motion in human cells. To break symmetry, all cells polarize making one part of the cell structurally, functionally, or ...
