1.The force of gravity acting on a body weighing 50 kg on the moon is equal to 80 N. From these data, determine the acceleration of gravity to the moon. What is the force of gravity acting on this body on the earth? from. Determine the depth of the gorge. 3. How much will the speed of a body falling from a certain height without an initial vertical speed change in 1 s? 4. Why does the force of gravity of a body to the earth impart the same acceleration to all bodies? 5. What is the force of attraction of the Earth to the sun, if the radius of the Earth’s orbit r = 150,000,000 km, the mass of the earth is 6 * 10 (to the 24th degree) kg. The mass of the sun is 2 * 10 (to the 30th degree) kg?

1. Ft = mg
g = Fт / m = 80/50 = 1.6 – acceleration of gravity on the moon
Fт = mg = 50 * 10 = 500 – the force of gravity acting on this body on earth
2.s = gt’2 / 2 = 10 * 9/2 = 45 – the depth of the gorge
3.on 10
4.because g depends only on the planet / star itself
5.F = Gm1m2 / r’2 = 1.6 * 10’30
