Fields

Question 1

what is a force field?

Answer 1

an area in which an object experiences a non-contact force.

Question 2

what does the distance between the field lines represent?

Answer 2

the field strength

Question 3

how are Force fields formed?

Answer 3

formed during the interaction of masses, static charge or moving charges

Question 4

what are two types of fields and how are they formed ?

Answer 4

● Gravitational fields - formed during the interaction of masses
● Electric fields - formed during the interaction of charges

Question 5

similarities and differences of both fields

Answer 5

similarities :
- Forces both follow an inverse-square law
- Use field lines to be represented
- Both have equipotential surfaces

Differences:
- In gravitational fields, the force exerted is
always attractive, while in electric fields the
force can be either repulsive or attractive.

• Electric force acts on charge, while
  gravitational force acts on mass.
