The force that pulls a freely falling object towards the mass of a body is known as acceleration due to gravity, denoted by the symbol 'g'. Its unit of measurement is m/s2. The value of 'g' varies based on the mass of the body and its radius. Interestingly, the value of 'g' on the moon remains constant.
The acceleration due to gravity on the moon, or the value of 'g' on the moon, is a constant 1.625 m/s2.
Calculating Gravity on the Moon
The formula to calculate the acceleration due to gravity is:
Where:
G is the universal gravitational constant, G = 6.674×10-11 m3 kg-1 s-2.
M is the mass of the body, measured in kg.
R is the radius of the body, measured in m.
g is the acceleration due to gravity, measured in m/s2.
The moon's mass is 7.35×1022 kg, and its radius is 1.74×106 m.
Substituting these values into the formula, we get:
Hence, the value of 'g' on the moon is 1.625 m/s2.
Remember that the unit of acceleration is also used for the acceleration due to gravity.
We hope this explanation helped you understand the value of 'g' on the moon, along with the formula, definition, calculation, and SI units for acceleration due to gravity.
What does the value 9.8 m/s^2 for acceleration due to gravity imply?
The value 9.8 m/s^2 for acceleration due to gravity implies that for a freely falling body the velocity changes by 9.8 m/s every second.
Does mass have any effect on acceleration due to gravity?
The acceleration due to gravity is independent of the mass of the body.
What is the formula to calculate the force of attraction between two objects?
If m1 and m2 are the two masses separated by a distance d. According to the universal law of gravitation, the force of attraction between them is F = Gm1m2/d^2
What is free fall?
Freefall is defined as a situation when a body is moving only under the influence of the earth’s gravity. Since external force is acting on the ball, the motion will be accelerated.
What is the value of g on the moon?
The value of acceleration due to gravity on the moon is one-sixth of its value on the earth. It is equal to 1.625 m/s^2.
