gravitational/electric fields

Newton’s Law

every particle with mass in the universe attracts every other particle with a force which s directly proportional to the product of their masses and inversely proportional to the square of the distance between their centres

weight

the gravitional force the earth exerts on any object on or near its surface

DEFINE gravitational fields

the force acting per unit mass

electric field

a region of space in which an electric charge experiences a force. the direction of the electric field at a point is the direction that a positive test charge would move if placed at that point

Coulomb’s Law

two point charges exert forces on each other. the force is directly proportional to the product of the charges and inversely proportional to the square of the distance between the charges

DESCRIBE gravitational field

a region of space where a mass will experience a force
