For a planet of uniform density how would the magnitude of the gravitational field halfway to the center compare with the field at the surface? The gravitational field halfway to the center will be half of the gravitational field at the surface.

6.67×10−11N.
What is a gravitational field and how can its strength be measured quizlet?
What is a gravitational field and how can its strength be measured? a. It is a force field on a body with mass with direction and magnitude equal to the inverse square of the distance to a test mass.
How do you find the magnitude of a gravitational field?
This is a way of measuring how much gravity there is. The formula is: weight/mass = gravitational field strength. On Earth the gravitational field strength is 10 N/kg.
What is the magnitude of their gravitational force of attraction?
Answer: The magnitude of the force of gravity between the spheres can be found using the gravitational force formula: The magnitude of the gravitational force between the two spheres is 1.6675 x 10–5 N (Newtons).
What is the magnitude of the gravitational acceleration on this planet?
…
The Value of g Depends on Location.
| Location | Distance from Earth’s center (m) | Value of g (m/s2) |
|---|---|---|
| Earth’s surface | 6.38 x 106 m | 9.8 |
| 1000 km above surface | 7.38 x 106 m | 7.33 |
Is gravity and gravitational field the same?
gravity force (weight) is measured in newtons (N) mass is measured in kilograms (kg) gravitational field strength (g) is measured in newtons per kilogram (N/kg)
What is surface gravitational field?
The surface gravity g of an astronomical object is the gravitational acceleration experienced at its surface at the equator including the effects of rotation.
What is gravitational field of Earth?

What is the magnitude of the gravitational force acting on the earth due to the sun?
What is the magnitude of the gravitational force exerted by a 15kg mass?
a2 = Gm10.252 =6.673∗10−11∗150.252= 1.6*10−8 ms2.
What is the magnitude of the gravitational force between the earth and a 2 kg object on its surface?
What is the magnitude of gravitational force between two 1 kg bodies that are 1’m apart quizlet?
Then do the same with the equation. What is the magnitude of the gravitational force between two 1-kg bodies that are 1m apart? 5. The gravitational force between is 6 ´ 10-11 N.
Do tides depend more on the strength of gravitational pull or the difference in strengths?
Do tides depend more on the strength of gravitational pull or on the difference in strengths? Explain. B) Tides depend only on the difference. … The sun exerts a stronger force on the side of Earth furthest from the Sun and the Moon exerts a stronger force on the side nearest the Moon.
What does the law of universal gravitation state quizlet?
Newton’s law of universal gravitation states that any two bodies in the universe attract each other with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. Density is mass/volume.
What does gravitational force depend 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 is gravitational field formula?
F= frac{GMm}{r^{2}} The gravitational force or the weight acting on a mass m in the gravitational field ? is given by: ? = m?. At the surface of the Earth ? has a magnitude of frac{GM}{R^{2}_{E}}= 9.81 ms^{-2} where R_{E} is the radius of the Earth.
How do you find the mass of gravitational field strength?
For a given gravitational field strength the greater the mass of the object the greater its weight. Weight can be calculated using the equation: weight = mass × gravitational field strength.
How do you find the mass of gravitational force?
- This law can be summed up with the equation F = ma where F is the force m is the mass of the object and a is acceleration.
- Using this law we can calculate the force of gravity of any object on the surface of the earth using the known acceleration due to gravity.
How do you calculate gravitational force on a satellite?
What is the gravitational force on a satellite?
True weightlessness only occurs in deep space where the gravitational force on an object is zero. A satellite in a stable circular orbit around Earth is continually in free fall. As it orbits it experiences a gravitational force towards the centre of Earth which causes it to change direction and ‘fall’ towards Earth.
How do you calculate gravitational acceleration on Earth?
These two laws lead to the most useful form of the formula for calculating acceleration due to gravity: g = G*M/R^2 where g is the acceleration due to gravity G is the universal gravitational constant M is mass and R is distance.
How do you calculate the gravitational acceleration of a planet?
- Gravitational Acceleration: g = (G × Mass)/(distance from the center)2.
- Comparing gravitational accelerations: acceleration at position A = acceleration at position B × (distance B/distance A)2.
- Calculating mass: Mass = (g × distance2)/G.
What is the value of g’in Centre of Earth?
The value of g at the centre of the earth is zero.
Do gravitational fields exist everywhere?
There is gravity in space – lots of it. Gravity is everywhere. … Because gravity is everywhere in space objects in space are always falling: towards the earth towards the sun and towards the galactic center. There are two reasons that objects seem to be floating without gravity in space when they are really falling.
How is the strength of the gravitational field represented in a gravitational field diagram?
Answer: Each field line has a direction marked on it with an arrow that shows the direction of the gravitational field at all points along the field line. The relative strength of the gravitational field is indicated by the density of the field lines (i.e. by how close the lines are).
Do gravitational fields exist?
No material medium is necessary for a gravitational field to exist—the field extends even through vacuum. The strength of the gravitational field due to an object is proportional to the mass of the object and the strength decreases with distance away from the object as 1/r2.
What type of field is a gravitational field?
Why is the gravitational field considered a field?
The gravitational field of every object is a radial field since the mass is concentrated at the objects centre and as you already know this is the point at which gravity could be said to act. As you can see a quarter of lines of force goes through the plane when the distance is doubled.
