1
Q
Define Electric Potential.
A
The work done per unit charge to move an object to a particular point in a field.
2
Q
State Newton’s universal law of gravitation.
A
The attractive force between 2 point masses is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
3
Q
Define gravitational field strength.
A
The force per unit mass that an object experiences in a field.
4
Q
Define gravitational potential.
A
The work done per unit mass to bring an object from infinity to a point in a gravitational field.
5
Q
State Coulomb’s Law.
A
The force between 2 positive point charges is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.
