What does the gravitational constant (G) represent?
Think about how mass and distance play roles in gravitational interactions.
Who first measured the gravitational constant?
Recall the experiment involving lead spheres.
The gravitational constant G is approximately equal to:
It’s quite small compared to other constants you might know.
Cavendish's experiment was primarily aimed at measuring what?
Recall the historical context of his findings.
If the distance between two masses is increased by a factor of three, how does the gravitational force change?
Recall how distance affects gravitational force.
Discuss how understanding G impacts our calculations of celestial bodies.
Think about the role of gravitational forces in orbiting bodies.
