Investigation 2.2 Force of gravity
​

2
We will be studying this data to learn more about the acceleration of gravity on different celestial objects
Estudiaremos estos datos para aprender más sobre la aceleración de la gravedad en diferentes objetos celestes

Data titles
Surface Gravitational Acceleration- force of gravity on each location Surface Gravitational Acceleration- aceleración gravedad en cada ubicación
Gravitational force (earth g)- Gravitational force on each plant, when compared to earths g (9.8) Fuerza gravitacional (tierra g)- Fuerza gravitacional en cada planta, en comparación con las tierras g (9.8)
Remember you can calculate the surface gravitational acceleration by multiplying earths g x the location's gravitational force in earth g's (mars: 9.8x .38) Recuerde que puede calcular la aceleración gravitacional de la superficie multiplicando las tierras g x la fuerza gravitacional de la ubicación en la tierra g's (marte: 9.8x .38)

Mass (Earth masses)- amount of matter in planet, when compared to Earth. Masa (masas terrestres)- cantidad de materia en el planeta, en comparación con la Tierra
Radius (earth radius)- distance to the center of the body (half of the diameter). Measured in comparision to Earth's radii. Radio (radio de tierra)- distancia al centro del cuerpo (la mitad del diámetro). Medido en comparación con los radios de la Tierra.

Why does Jupiter have the largest gravitational force of the planets? ¿Por qué Júpiter tiene la mayor fuerza gravitacional de los planetas?
6
Multiple Choice
Mercury and Mars have the same gravitational acceleration, but different masses. What other information do you see in the table that could cause this?
The radius
Mass
Gravitational acceleration
7
The other date that varies is the diameter of the planets. So it could have something to do with the size (diameter) of the planet.
Los otros datos que varían es el diámetro de los planetas. Así que podría tener algo que ver con el tamaño (diámetro) del planeta.

Multiple Choice
Uranus is more massive than Earth, but has less gravitational acceleration. Which planet has a larger radius?
Urano es más masivo que la Tierra, pero tiene menos aceleración gravitacional. ¿Qué planeta tiene un radio mayor?
Uranus
Urano
Earth
La Tierra
9
Multiple Choice
Saturn is more massive than Neptune, but has less gravitational acceleration. Which planet has a larger diameter?
Saturno es más masivo que Neptuno, pero tiene menos aceleración gravitacional. ¿Qué planeta tiene un diámetro mayor?
Saturn
Saturno
Neptune
Neptuno

The Gravitational force between two objects is related to the distance from their center of mass. This means the farther you are from the center of an object, in this case the larger planet's diameter, the weaker the gravitational force will be.
La fuerza gravitacional entre dos objetos está relacionada con la distancia desde su centro de masa. Esto significa que cuanto más lejos estés del centro de un objeto, en este caso el diámetro del planeta más grande, más débil será la fuerza gravitacional.

(Write this in your notes)
(Escriba esto en sus notas)
As you increase the distance between objects (their centers of mass). their gravitational force decreases.
A medida que aumenta la distancia entre los objetos (sus centros de masa). su fuerza gravitacional disminuye.
the further you are froom the cemter of an object- in this case the larger the planet's diameter, the weaker the gravitational pull will be
