Optical forces allow manipulation of small particles and control of nanophotonic structures with light beams. While some techniques rely on structured light to move particles using field intensity ...

Tissues and cells in the human body are subjected to a constant push and pull - strained by other cells, blood pressure and fluid flow, to name a few. The type and direction of the force on a cell ...

A force is a push or a pull. For example, when you push open a door you must apply a force to the door. You also must apply a force to pull open a drawer. You cannot see a force but often you can see ...

You have a wire that is carring an AC current through a magnetic field caused by two magnets. The current flowing in the wire is in the X direction and the magnetic field is in the Y direction. In ...

Isaac Newton's First Law of Motion states, "A body at rest will remain at rest, and a body in motion will remain in motion unless it is acted upon by an external force." What, then, happens to a body ...
