How much would the time keeping of a pendulum clock be affected by taking it to the moon? Gravity is 1.6m/s ^2, compared with 10m/s ^2 on the earth.

Answer 1

period=2PIsqrt(length/g)
so if g is reduced from 9.8 to 10. UGH it is not 10m/s^2 on earth. Get a new teacher.

periodchange= sqrt (1.6/9.8) that is the factor it is changed by, going much slower.
