PHYSICS COULOMB FORCE GIZMO
COMPREHENSIVE STUDY GUIDE 2026
◉ Do opposite charges attract or repel? Why? Answer: They attract
because opposites always attract.
◉ Do like charges attract or repel? Why? Answer: They repel
because they are both positive.
◉ If a negatively charged object is near a neutral object, which
charges move? Answer: Electrons would move to balance each other
out.
◉ What are the units of charge? Answer: Coulombs (C).
◉ How can you increase the force between two charges? Answer:
Increase the charge of both charges or decrease the distance
between them.
◉ What is the charge of a negatively charged object? Answer:
Negative.
, ◉ If one charge is doubled, what happens to the electric force?
Answer: The force is doubled.
◉ If both charges are doubled, what happens to the electric force?
Answer: The force is quadrupled.
◉ If the distance between two charges is doubled, what happens to
the electric force? Answer: The force becomes one fourth.
◉ What happens to gravitational force if the distance is halved?
Answer: The gravitational force increases.
◉ What happens to gravitational force if the distance is doubled?
Answer: The force decreases.
◉ What happens to gravitational force if the distance is tripled?
Answer: The force goes down.
◉ What happens to gravitational force if the mass of one object is
halved? Answer: The force goes down
◉ What happens to gravitational force if the mass of both objects
doubles? Answer: The force goes up.
