Exploring Newton’s Law of Universal Gravitation Through PhET
Central to the PhET gravity force simulation is Newton’s law of universal gravitation, which
states that every two masses attract each other with a force proportional to the product of
their masses and inversely proportional to the square of the distance between them.
Mathematically, this is expressed as:
\[ F = G \frac{m_1 m_2}{r^2} \]

m₁ and m₂ are the masses.
3.
r is the distance between the centers of the two masses.
4.
How the Simulation Demonstrates This Law
In the PhET simulation, as you increase one or both masses, the gravitational force
vectors grow longer, indicating stronger attraction. Conversely, increasing the distance
between the objects causes the vectors to shrink in length, showcasing the inverse square
relationship. The answer key typically provides sample calculations that confirm these
observations, helping learners connect the visual representation with the formula.
