5.1 Force Fields Flashcards
Define a gravitational field
a region of space in which a mass will experience a force
Define an electric field
a region of space in which a charge will experience a force
Define a magnetic field
A region of space in which a moving charge (or an electric current) will experience a force
The direction of the field at any time is given by the ————— what to the field line
tangent
Why can’t field lines cross?
This would mean that the field would have more than one direction at that point, which is a contradiction
What do closer together field lines say about the field?
The field is stronger
What do closer together field lines say about the field?
The field is stronger
What do the field lines of a uniform field look like?
parallel and equally spaced
Describe a field with radial field lines
non-uniform field
