Which system has the strongest gravitational field?
Jupiter
What has the smallest gravitational field strength?
Summary: Researchers have succeeded in measuring the gravitational field of a gold sphere, just 2 mm in diameter, using a highly sensitive pendulum – and thus the smallest gravitational force.
What is the gravitational field strength of the planets?
| Planet | Diameter (Compared to Earth) | Gravitational Field Strength |
|---|---|---|
| Earth | 1 | 10 N/kg |
| Mars | 0.5 | 4 N/kg |
| Jupiter | 11 | 23 N/kg |
| Saturn | 9 | 9 N/kg |
How many G’s can kill you?
Changes in speed are expressed in multiples of gravitational acceleration, or ‘G’. Most of us can withstand up to 4-6G. Fighter pilots can manage up to about 9G for a second or two. But sustained G-forces of even 6G would be fatal.
What does 9.81 mean?
It has an approximate value of 9.81 m/s2, which means that, ignoring the effects of air resistance, the speed of an object falling freely near the Earth’s surface will increase by about 9.81 metres (32.2 ft) per second every second.
How was g calculated?
The value of G was not experimentally determined until nearly a century later (1798) by Lord Henry Cavendish using a torsion balance. Once the torsional force balanced the gravitational force, the rod and spheres came to rest and Cavendish was able to determine the gravitational force of attraction between the masses.
Why is G called a universal constant class 9?
G is called universal constant becuase its value remains the same throughout the universe and is independent of masses of the objects. Answer: Capital G will be constant become the value of the G will be constant anywhere in the Universe.
Why is GA universal constant?
G is called the universal gravitational constant since it has a constant value all throughout the Universe.
What is the difference between G and G?
g is the gravitational force exerted by any planet. For earth it’s 9.8m/s2. G can be g but g cannot be G….question_answer Answers(5)
| Acceleration due to gravity ( g ) | Universal Gravitation Constant ( G ) |
|---|---|
| Value of g=9.8 m/s2 | Value of G=6.673×10-11 Nm2/kg2 |
What is relation between G and G Class 9?
The acceleration on an object due to the gravity of any massive body is represented by g (small g). The force of attraction between any two unit masses separated by unit distance is called universal gravitational constant denoted by G (capital G).
What is free fall differentiate between G and G?
| Acceleration due to Gravity (g) | Universal Gravitational Constant (G) |
|---|---|
| -> Value of g near earth’s surface is 9.8ms−2 . It may vary from one place yo place . | -> Value of G is 6.67×10−11Nm2kg−2 and it is an universal constant |
| Depends upon the distance between the masses | Independent of the distance between the masses |
What is the relationship between G and G in physics?
g is the acceleration due to the gravity of any given body in m.s. G is the universal gravitational constant in Nm2.kg. R is the radius of the given body in km. M is the mass of the given body in kg.
Is value of g same everywhere?
The value of g at all place is not the same, it varies. The value of g is more at the poles and less at the equator. Hence on the basis of altitude the value of g changes.
What is acceleration due to gravity explain formula of relation between G and G find the value of G Class 9?
Acceleration due to gravity is the acceleration gained by an object due to gravitational force. Its SI unit is m/s2. Acceleration due to gravity is represented by g. The standard value of g on the surface of the earth at sea level is 9.8 m/s2.
