Coulomb Force vs. Gravitational Force and Superposition Principle

Vocabulary flashcards based on lecture notes about Coulomb force, gravitational force, and superposition principle.

Coulomb Force

Force that may be attractive or repulsive and depends upon the medium.

Gravitational Force

Force that is always attractive in nature and does not depend upon the medium.

Coulomb Force characteristic

The force between charges will not be the same during motion or rest with a high value of K=9x10^9 Nm^2 C^-2

Gravitational Force characteristic

It is always the same whether the two masses are at rest or in motion with a value of G is 6.67 x 10^-11 Nm^2 kg^-2

Superposition Principle

According to this principle, the total force on a given charge is the vector sum of the forces exerted on it by all other charges.
