What is the relationship between distance from the center of the Earth & Pressure?
The gravitational force, F, between an object and the earth is inversely proportional to the square of the distance from the object and the center of the earth.
What is the relationship between the acceleration due to gravity and the distance from the Centre of the Earth?
The acceleration of an object changes with altitude. The change in gravitational acceleration with distance from the centre of Earth follows an inverse-square law. This means that gravitational acceleration is inversely proportional to the square of the distance from the centre of Earth.
What is the type of relationship between gravitational field strength and distance?
The gravitational field strength is directly proportional to mass creating the field and inversely proportional to the square of the distance.
What is the difference between gravitational field and gravitational field strength?
What is the difference between gravitational potential energy and gravitational field strength? Gravitational Potential Energy is the work done in moving a mass from infinity to a point in a gravitational field. On the other hand, Gravitational Field Strength is the force exerted per unit mass on a small test mass.
What is the relation between acceleration due to gravity and gravitational constant?
What is G and g?
| Symbol | Nature of Value | |
|---|---|---|
| Acceleration due to gravity | g | Changes from place to place. Acceleration due to gravity of the earth is 9.8 m/s2 |
| Universal Gravitational Constant | G | Constant at any point in this universe. G = 6.67×10-11 Nm2/kg2 |
What is the strength of the gravitational field at the center of Earth?
The gravitational field at Earth’s center is zero.
Does gravitational field strength vary?
The weight of an object and the gravitational field strength are directly proportional. For a given mass, the greater the gravitational field strength of the planet, the greater its weight….Gravity on other objects in space.
| Space object | g, gravitational field strength (N/kg) |
|---|---|
| Neptune | 11.7 |
| Pluto (dwarf planet) | 0.49 |
What is the relationship between force of gravity and distance?
The inverse relationship between the force of gravity and the distance between two objects is based on the square of that distance. This means that if the distance is doubled, the gravitational force is decreased by a factor of 4. This is because the square of 2 is 2 x 2, which equals 4.
How does the Earth’s gravitational field change with distance?
the Earth’s gravitational pull acts towards the centre of the Earth the Earth’s gravitational field is radial; the field lines become less concentrated with increasing distance from the Earth. The force exerted on an object in a gravitational field depends on its position. The less concentrated the field lines, the smaller the force.
What is the gravitational force at the center of the Earth?
The gravitational field strength at its centre is zero, since attractive forces pull equally in all directions. Beyond the surface of the Earth, the gravitational force on an object decreases with increasing distance.
What is the direction of the gravitational field strength?
Gravitational field strength is a vector quantity: its direction is towards the object that causes the field. Always use the given value for g. Candidates often lose marks for using 10ms –2 when the formula sheet gives g = 9.81ms –2 In studying gravitation, Newton concluded that the gravitational attractive force that exists between any two masses:
