Gravitational and electric fields Flashcards
1
Q
Newton’s 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
weight
A
the gravitational force the Earth exerts on
any object on or near its surface
3
Q
gravitational field
A
the force acting per unit mass
4
Q
Coulomb’s law
A
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
5
Q
electric field
A
the force per unit positive
charge
