Question

gravity is the force that causes smaller celestial objects to orbit around larger ones. an orbit is a nearly circular or oval - shaped path that one object travels around another. for example, the moon orbits earth along a slightly oval - shaped path.
over four billion years ago, the forces from the moon’s creation set it in motion. because there is no air resistance in space to slow it down, the moon continuously orbits earth at a speed of about 3,683 kilometers per hour.
this model shows the relationship between earth’s gravitational pull on the moon and the moon’s forward motion.
an image showing the orbital path of the moon around the earth, with arrows indicating gravity (towards earth) and forward motion (tangential to the orbit)
select the true statements.

• earth’s gravitational pull keeps the moon in orbit around it.
• gravity causes smaller celestial objects to orbit around larger ones.
• earth’s gravitational pull is parallel to the moon’s forward motion.
• orbits are nearly circular or oval - shaped paths that celestial objects travel around other celestial objects.

Explanation:

• Para "Earth’s gravitational pull keeps the Moon in orbit around it": El texto dice que el modelo muestra la relación entre la atracción gravitacional de la Tierra sobre la Luna y el movimiento forward de la Luna, y la gravedad es la fuerza que hace que los objetos celestes más pequeños orbiten alrededor de los más grandes, por lo que la atracción gravitacional de la Tierra mantiene a la Luna en órbita. Esta es verdadera.
• Para "Gravity causes smaller celestial objects to orbit around larger ones": El primer párrafo dice "Gravity is the force that causes smaller celestial objects to orbit around larger ones", así que esta es verdadera.
• Para "Earth’s gravitational pull is parallel to the Moon’s forward motion": En la imagen, la flecha de la gravedad (atracción de la Tierra) es horizontal hacia la Tierra, y la flecha del movimiento forward es vertical hacia abajo, por lo que no son paralelas. Esta es falsa.
• Para "Orbits are nearly circular or oval - shaped paths that celestial objects travel around other celestial objects": El primer párrafo dice "An orbit is a nearly circular or oval - shaped path that one object travels around another" y el ejemplo es la Luna orbitando la Tierra (objetos celestes), así que esta es verdadera.

Answer:

• Earth’s gravitational pull keeps the Moon in orbit around it.
• Gravity causes smaller celestial objects to orbit around larger ones.
• Orbits are nearly circular or oval - shaped paths that celestial objects travel around other celestial objects.
