Newton’s Law of Gravitation
What is Newton's Law of Gravitation?
This law describes the gravitational force between two masses at a given distance.
Kepler’s First Law states that the orbit of a planet around the Sun is shaped like this.
What is an ellipse?
This was the launch year for NASA’s Juno mission to Jupiter.
What is 2011?
Juno’s mass is constant, but this force changes depending on its distance from Jupiter.
What is gravitational force?
What is the gravitational constant?
This constant, represented by GGG, is used in Newton's Law of Gravitation to calculate force between two masses.
The Juno mission adjusted its orbit to this many days due to concerns about the probe’s fuel valves.
What is 53 days?
One objective of the Juno mission was to map these two fields of Jupiter.
What are magnetic and gravity fields?
This term describes the effect of gravitational force on an object’s mass.
What is weight?
In Newton’s Law of Gravitation, if the distance r between two objects doubles, the gravitational force changes by this factor.
What is one-fourth?
According to Kepler’s Second Law, Juno moves faster when it is in this part of its orbit around Jupiter.
What is the closest point (periapsis or perijove)?
When Juno is 5000 km away from Jupiter, the gravitational force it experiences is greater by this factor compared to a point 8 million km away.
What is 1600?
When Juno moves from a high orbit to a low orbit, this variable in Newton’s Law of Gravitation decreases, increasing the gravitational force.
What is distance?
The gravitational force between two objects depends on these two factors.
What are mass and distance?
The ratio T2/R3T^2/R^3T2/R3, based on Kepler’s Third Law, is approximately this value for planets orbiting the Sun.
What is 1?
This is the primary reason why scientists needed to distinguish Juno’s orbit from the orbits of Jupiter’s moons.
What is to avoid collision with the moons?
Jupiter’s mass affects Juno’s orbit by exerting this type of force.
What is gravitational force?
The mass of Juno remains constant, but this property changes when it orbits closer or farther from Jupiter.
What is weight?
The shape of planetary orbits, as described by Kepler’s First Law, affects how fast planets move along their paths based on this factor.
What is distance from the Sun or other focus?
This unit of distance, represented by AU, is based on the average distance between the Earth and the Sun.
What is an astronomical unit?
If the mass of Jupiter were doubled, this would happen to the gravitational force on Juno at a constant distance.
What is it would double?
