Which configuration will result in the greatest gravitational force? The two bottom configurations result in the greatest force because gravity increases when object get closer and gravity increases when mass increases. What does Kepler’s first law of planetary motion state?
For Which Star Will the astronomer observe the greatest Parallax?
According to Copernicus, what causes the year and seasons on Earth? An astronomer observes four stars from two different locations on Earth. Will the astronomer observe the greater parallax for a star that is closer to Earth or farther from Earth? the greater parallax for a star that is closer from Earth .
What is gravitational force quizlet?
Gravitational Force. An attractive force that acts between any two objects . Universal Law of Gravitation.
What force pulled the solar system together out of a cloud of gas and dust?
Approximately 4.5 billion years ago, gravity pulled a cloud of dust and gas together to form our solar system.
What two factors affect gravitational force quizlet?
Two factors affect the gravitational attraction between objects: mass and distance .
Who invented parallax method?
The first successful measurements of stellar parallax were made by Friedrich Bessel in 1838 for the star 61 Cygni using a heliometer.
What is the parallax formula?
The parallax formula states that the distance to a star is equal to 1 divided by the parallax angle, p , where p is measured in arc-seconds, and d is parsecs.
What two factors affect gravitational pull?
When dealing with the force of gravity between two objects, there are only two things that are important – mass, and distance . The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them.
What is the relationship between mass and gravitational force quizlet?
What is the relationship between gravitational force and mass? The higher the mass the higher the gravitational force is . They move at a very constant rate meaning if the mass goes up by x, then the gravitational force will go up by x. When mass goes up the force goes up, but when distance goes up the force goes down.
Who discovered the gravitational force of Earth?
Sir Isaac Newton was an English mathematician and mathematician and physicist who lived from 1642-1727. The legend is that Newton discovered Gravity when he saw a falling apple while thinking about the forces of nature.
How was the solar system formed step by step?
Our solar system formed about 4.5 billion years ago from a dense cloud of interstellar gas and dust. The cloud collapsed, possibly due to the shockwave of a nearby exploding star, called a supernova. When this dust cloud collapsed, it formed a solar nebula – a spinning, swirling disk of material.
What is the difference between condensation and accretion?
Condensation is the building of larger particles one atom (or molecule) at a time, whereas accretion is the sticking together of larger particles . ... The planets swept up gas, dust, and small particles.
How did our solar system begin to form quizlet?
The solar system formed 4.6 billion years ago from a swirling, disk-shaped cloud of gas, ice, and dust , called the solar nebula. ... The planets and other debris in the solar system today formed from gas, ice, and dust in the solar nebula orbiting the protosun.
What are three things that gravitational force depends on?
The magnitude of this force depends upon the mass of each object and the distance between the centers of the two objects . Mathematically, we say the force of gravity depends directly upon the masses of the objects and inversely upon the distance between the objects squared.
What are the two factors that affect friction quizlet?
The strength of the force of friction depends on two factors: how hard the surfaces push together and the types of surfaces involved .
What 3 factors affect the pull of gravity?
Two major factors, mass and distance , affect the strength of gravitational force on an object.
