Gravitational And Electric Fields Flashcards
1
Q
Newton’s law of universal gravitation
A
Every particle with a mass 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
Weight
A
The gravitational fire the earth exerts on any object on or near its surface
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
A region of space in which an electric charge experiences a force
5
Q
Magnitude of the electric at a point
A
The force per unit charge
