How is newton's law related to satellite orbit?

Answer 1

Yes of course. The gravity is the one responsible for keeping the satellite in place. But hold your horse how can that be possible. If the gravity was the only force acting then the satellite should start moving in a spiral fashion thereby crashing down on the earth surface. Here we see the action of something called the centrifugal force which is one of the famous pseudo forces.

Now what is a pseudo force? Well these are the forces which does not exist in reality. It is something which you assume to exist to counter balance the other force that is keeping you spinning called the centripetal force(like gravity in case of satellites). Even you feel this force like when you're standing inside a bus and the bus takes a sharp turn and you tilt the other way.

Answer 2

acceleration toward each other is from a = (G*(m1+m2))/r^2 (pull of gravity).

this is balanced using a = v^2/r (centripetal action).

G = newtons gravitational constant (6.67 * 10^-11)

m1 = mass earth (5.97 * 10 ^24 kg)

m2 = sattelite mass (kg)

r = orbital radius (metres)

v = orbital velocity (metres/sec)

for any given orbital radius, only one velocity will keep it there (in balance), so the orbit time is fixed to the orbital radius

Answer 3

Newton's law of universal gravitation states that any two objects attract each other with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. This law is crucial for understanding the motion of satellites in orbit around a celestial body, as it governs the gravitational force that keeps the satellite in its orbital path. By knowing the mass of the planet or star being orbited and the distance between the satellite and the celestial body, along with the satellite's velocity, we can calculate and predict its orbital motion.
