PHYSICS COULOMB FORCE GIZMO KEY
CONCEPTS AND APPLICATIONS GUIDE 2026
◉ According to Coulomb's Law, what will happen to the force
between two charged particles if the magnitude of both charges are
increased 6 times and the distance between them is increased 6
times? Answer: The force will remain the same
◉ If all of the variables in Coulomb's law are increased to 7 times
larger, how much different is the new force as compared to the
previous force? Answer: no change in the force
◉ Coulomb's Law says that the force between any two charges is
Answer: directly related to the size of the charges AND inversely
related to the square of the distance between charges
◉ The value of k (the electrical constant in Coulomb's Law)...
Answer: never changes
◉ What is a strength of limitation of the model below comparing the
Gravitational Force and the Electrostatic Force? Answer: Strength:
The model shows how the direction of force differs between
Gravitational and Electrostatic Forces
, Weakness: The model does not show that the Electrostatic Force is
much stronger than the Gravitational Force
◉ Select all of the following that describe by Coulomb's Law ONLY
Answer: *varies directly with charge
*contains a constant
*varies directly with mass
*force of repulsion
*force of attraction
◉ Select all of the following that describe by Newton's Law of
Universal Gravitation ONLY Answer: *varies directly with mass
*force of repulsion
*varies directly with charge
*varies inversely with distance squared
*contains a constant
*force of attraction
◉ Which of the following symbols appear in the formula for both
Coulomb's Law and Newton's Law of Universal Gravitation? Answer:
*G
*d^2
*k
