Question

Calculate the acceleration due to gravity on the Moon. The Moon's radius is 1.74x10^6m and it's mass 7.35x10^22kg

Answer 1

Acceleration due to gravity on the moon is 1.624 m/
`s^2`

Explanation:

Given

M is the mass of the moon=
`(7.35* 10^(22))` kg

r is the radius of the moon in =
`(1.74* 10^6)`

G is the gravitational constant
`6.67 *10^-11`
`Nm^2/kg^2`

Solution:

Acceleration due to gravity g =
`(GM)/(r^2)`=
`\frac{(6.67 * 10^-11)*(7.35 * 10^22)} {(1.74*10^6)^2}=1.624m/s^2`
