Question: What is the acceleration due to gravity at the Moon’s surface? Moon’s mass = 7.35 x 1022 kg, the radius of the Moon is 1.7 x 106 m, universal constant is 6.67 x 10-11 N m2 / kg2


Given values are

Moon's mass (M) = 7.35 x 1022 kg

Radius of the moon (r) = 1.7 x 106 m

Universal constant (G) = 6.67 x 10-11 N m2 / kg2

Acceleration due to gravity at Moon's surface g = GM / r2

g = (6.67 x 10-11 * 7.35 x 1022) / (1.7 x 106)2

= 16.19 x 10-1

g = 1.62

FAQs on Acceleration due to Gravity Calculator

1. What is the formula for acceleration due to gravity?

Acceleration due to Gravity formula is g = GM / r2

Where G is the Universal gravitational constant, M is the mass, and r is the radius.

2. What is Acceleration due to gravity?

Acceleration due to gravity is the instantaneous change in downward velocity (acceleration) caused by the force of gravity toward the center of mass. It is typically experienced on large bodies like planets, moons, stars and asteroids but can occur minutely with smaller masses.

3. What is the acceleration due to gravity called?

Acceleration due to gravity is also called free-fall acceleration. Masses generate gravitational fields that attract other masses.

4. Is acceleration due to gravity positive or negative?

g always acts downwards and is a positive number i.e 9.8 m / s2. It can be positive or negative based on the sign you assign to upward and downward direction.
