force field

Force field may refer to:

• Force field (fiction), a barrier made up of energy or particles to protect a person, area or object from attacks or intrusions or as a means of containment or confinement
• Force field (physics), a vector field indicating the forces exerted by one object on another
• Force field (chemistry), a set of parameter and equations for use in molecular mechanics simulations
• Force-field analysis, a concept in the social sciences
• Force field (neuroscience), a region in the spinal cord that causes limbs to exert a consistent force depending on the limbs' position
• Forcefield (art collective) and band from Providence, Rhode Island associated with Fort Thunder
• Forcefield (band), a British rock band featuring Graham Bonnet, Cozy Powell, Peter Prescott, Neil Murray and Ray Fenwick
• "Force Field", the theme tune of the British game show The Crystal Maze

In fictional works, a force field, sometimes known as an energy shield, force shield, or deflector shield, is a barrier made of energy or particles. It protects a person, area, or object from attacks or intrusions. This fictional technology is created as a field of energy without mass that acts as a wall, so that objects affected by the particular force relating to the field are unable to pass through the field and reach the other side. Scientific research into real force fields is ongoing, primarily to protect against radiation.
