Yes I do understand what the equation: Fg = Gm1m2 / r^2 this is what my notes say (taking an online physics course, they provide notes) G = gravitational field constant, m1 and m2 are the two masses, Fg = the force of gravity acting on each object, r = the distance between the centres of...

Homework Statement A 12 kg meteor experiences an acceleration of 7.2 m/s^2, when falling towards the earth. a.) How high above the Earth's surface is the meteor? b.) What force will a 30 kg meteor experience at the same altitude? Homework Equations Fg = ma , Fg =Gm1m2 / r^2...

Okay, thank you! So is my calculation correct??

Hi guys and thank you!And thank you very much for clarification sleepy_time, I appreciate it. So would it be this then? distance from rocket to the moon: Δd = 3.84E8 - 3.0E 8 Δd = 8.4E7 m Thus, Fg = (6.67E-11)(7.35E22)(1200) / (8.4E7)^2 Fg = 0.83375 N FgNet = 5.3182 + (-0.83375 N) FgNet...

Homework Statement The Earth has a mass of 5.98x10^24 kg and the moon has a mass of 7.35x10^22 kg. The distance from the centre of the moon to the centre of the Earth is 3.84x10^8 m. A rocket with a total mass of 1200 kg is 3.0x10^8 m from the centre of the Earth and directly in between Earth...
