GRAVITATIONAL & ELECTRIC FIELDS Flashcards
1
Q
newtons law of universal gravitation
A
every particle with mass in the universe attracts every other particle with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centres.
2
Q
gravitational field
A
the force acting per unit mass (as the region in space where a mass will experience a force.)
3
Q
coulomb’s law
A
two point charges in free space or air 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
4
Q
electric field
A
as a region of space in which an electric charge experience a force.
5
Q
magnitude of the electric field
A
the force per unit positive charge
