Section 7.1: Fields Flashcards
1
Q
What is a force field?
A
An area in which an object experiences a non-contact force.
2
Q
What are the two ways force fields can be represented?
A
Vectors
Diagrams with field lines
3
Q
What does the distance between field lines represent?
A
The strength of the force exerted by the field in that region.
4
Q
State 3 similarities between electric and gravitational fields
A
Follow an inverse-square law
Use field lines to be represented
Have equipotential surfaces
5
Q
State 2 differences between electric and gravitational fields
A
In gravitational fields, the force exerted is always attractive, while in electric fields it can be attractive or repulsive.
Electric fields act on charge, while gravitational fields act on mass.
