Fields Flashcards
(8 cards)
What is a force field
An area in which an object experiences a non-contact force
2 ways to represent force fields
Vectors or diagrams containing field lines
What feature of field lines represent strength of force exerted
Distance between them
When are force fields formed
During interaction of masses, static charges or moving charges
When are gravitational fields formed
During interaction of masses
When are electric fields formed
During interaction of charges
3 similarities of gravitational and electric fields
Forces both follow an inverse-square law, use field lines to be represented, both have equipotential surfaces
2 differences of gravitational and electric fields
Gravitational fields only attractive, electric can be attractive or repulsive, electric field acts on charge, gravitational acts on mass
