1.

Calculate the force of gravity on a 1 kg mass at Earth’s surface. The mass of the Earth is 6 x 10^24 kg, and its radius is 6.4 x 10^6 m.

Asemmisa {{asɛmmisaAhyɛnsode}}
2.

Calculate the force of gravity between Earth (mass = 6x10^24 kg) and the moon (mass = 7.4x10^22 kg). The average Earth-moon distance is 3.8x10^8 m.

3.

What gravitational attraction does the moon have for a 70 kg person on earth? Use this info for the following question: mass of moon=7.4x10^22 kg, and distance between earth and moon is 3.8x10^8 m.
