hi! gravitational force is what keeps on ground, in simple terms. if there wasn't any gravitational force life would have been very difficult. imagine staying in the air for the whole of ur life. isaac newton discovered this force. he was sitting under the tree when an apple fell on his head and he started to study about the force that caused the apple to fall on tthe ground. the gravitational force on earth is grater than thath of the moon. if u weigh 60 on earth u'll wigh 10 on moo. the gravitational force of the moon is 1/6th of that of the earth. all the planets move around the sun because of thye sun's gravitational force.
bye!

Isaac Newton discovered it. He came up with the idea when sitting under an apple tree and got bonked on the head by a falling apple. Don't you watch school house rock?
The gravitational force between two bodies of masses m and M offset by a vector distance r is given by
F= GMmr/rE3

Metallica's Load. I continuously positioned it on the again burner because I continuously take heed to oftentimes RtL or MoP when I take heed to Metallica, yet I picked up both Load and ReLoad low-cost at an independent music save very last summer season and got here across that I knew significantly better songs on Load than i idea I did and that it continues to be an all round relaxing album, regardless if it really isn't any longer precisely "metallic". yet although, what does "metallic" quite recommend in recent times besides?

gravitational force is the amount of pull of a body to the centre of the earth. should be newton who discovered it.

Gravity is a force acting on a body to make it fall when free.
Isaac newton discovered it.
