Coulomb’s Law: Coulomb Force Gizmo Answer Key
Coulomb’s Law is a fundamental law of physics that describes the electrostatic force between two charged particles. It was first formulated by Charles-Augustin de Coulomb in the 18th century and is one of the cornerstones of classical electromagnetism.
According to Coulomb’s Law, the force between two point charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. The force is also directed along the line connecting the two charges.
The mathematical equation for Coulomb’s Law is:
F = k

Coulomb Force Gizmo
The Coulomb Force Gizmo is an interactive simulation that allows students to investigate the electrostatic force between two charged objects.
The gizmo features two charged spheres that can be moved around the screen. The charges of the spheres can be positive or negative, and their magnitudes can be adjusted. The gizmo also includes a ruler that can be used to measure the distance between the spheres.
Using the Gizmo to Investigate Coulomb’s Law
Coulomb’s Law states that the electrostatic force between two charged objects is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. The Coulomb Force Gizmo can be used to investigate this law by varying the charges of the spheres and the distance between them and observing the resulting force.
To investigate Coulomb’s Law using the gizmo, follow these steps:
- Set the charges of the spheres to equal values but opposite signs.
- Move the spheres to different distances apart and observe the force between them.
- Record the force and distance measurements in a table.
- Plot the force versus the square of the distance.
The resulting graph should be a straight line with a slope equal to the Coulomb constant.
