Objects maintain a constant velocity unless acted upon by an outside force. Force=Mass times acceleration, force is proportional to mass or acceleration. No force occurs in isolation, it occurs in balanced pairs.
All planets orbit in an ellipse. The closer an object gets to the gravitational center, the faster the object goes. P2 = a3 .p= earth years. a= astronomical units An astronomical unit is the distance from the earth to the sun which is an average 93,000,000 miles
We concluded that these are amazing discoveries about space. If we didn’t have these laws/discoveries then we, as in the world, would be confused so much about space without these laws.
