The Falling Loop: Why Satellites Stay in Orbit

An orbit is not just sitting in space; it is actually a perpetual state of falling toward Earth and missing the ground every single time. By moving sideways fast enough, a satellite balances the pull of gravity with its own...

Questions: 20 | Attempts: 11 | Last updated: Feb 27, 2026

Sample Question 1
What two primary factors must be perfectly balanced to understand why satellites stay in orbit?

Gravity and magnetism

Heat and light

Gravity and inertia

Friction and speed

Electricity and weight

Sample Question 2
There is no gravity in the regions of space where satellites orbit the Earth.

True

False

Sample Question 3
Which famous scientist used a "cannonball" thought experiment to explain why satellites stay in orbit?

Albert Einstein

Isaac Newton

Galileo Galilei

Marie Curie

Thomas Edison
