Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Satellites that are in orbit are ____
A
constantly using rockets to stay in orbit
B
not experiencing gravity
C
are falling around the planet
D
going slightly faster than we drive on the interstate
Explanation: 

Detailed explanation-1: -Satellites can continue to orbit around the Earth without falling, because two powers – “gravity” and “centrifugal force” are keeping the balance. Gravity is the power that the Earth pulls satellites. Centrifugal force is the power that satellites tend to move away from the Earth by orbiting around it.

Detailed explanation-2: -The Short Answer: Satellites don’t fall from the sky because they are orbiting Earth. Even when satellites are thousands of miles away, Earth’s gravity still tugs on them.

Detailed explanation-3: -The closer satellites are to Earth the more likely it is that they will run into traces of Earth’s atmosphere which create drag. The drag decays the satellite’s orbit and causes it to fall back towards Earth.

Detailed explanation-4: -A satellite orbits Earth when its speed is balanced by the pull of Earth’s gravity. Without this balance, the satellite would fly in a straight line off into space or fall back to Earth. Satellites orbit Earth at different heights, different speeds and along different paths.

Detailed explanation-5: -Yes it does! On average, a total of between 200-400 tracked objects enter Earth’s atmosphere every year. That’s about one every day!
