The idea

What is Gravitation and orbits?

Gravitation and orbits concern the attractive force between any two masses and the paths it produces. Newton's law of gravitation says the force is proportional to the product of the masses and inversely proportional to the square of the distance between them. A satellite stays in orbit because gravity supplies exactly the centripetal force needed to keep bending its path around the planet; it is in continuous free fall that keeps missing the ground.

Where it appears: Class 9 and 11 CBSE, GCSE and A-level, IB Physics, AP Physics 1 and C, JEE and NEET.

Where learners get stuck

Why Gravitation and orbits is hard

Learners believe astronauts float because there is no gravity in space, when gravity is nearly as strong as on the ground and they are simply falling along with their spacecraft.

The picture a good explanation starts with: A planet with a cannonball fired from a mountain at increasing speeds, each trajectory curving further until one circles the planet completely as an orbit.

A lesson, step by step

How a lesson on Gravitation and orbits goes

  1. 01

    Ask

    Type or say "Why don't satellites fall back to Earth?" in your own words, in any of 26 languages.

  2. 02

    Plan

    The tutor plans a storyboard, one picture per idea, starting with a planet with a cannonball fired from a mountain at increasing speeds, each trajectory curving further until one circles the planet completely as an orbit.

  3. 03

    Explain

    It explains Gravitation and orbits out loud while the picture builds step by step, pitched to your level (Class 9 and 11 CBSE and up).

  4. 04

    Interrupt

    Say "wait, why?" or type a doubt: it stops, answers over the picture, and carries on. Ask for a different explanation any time.

  5. 05

    Check

    A checkpoint question makes sure the idea landed, and Test Lab keeps the practice going.

  6. 06

    Your notes

    Upload a PDF or a photo of your class notes or a past paper and the lesson follows your textbook's terms.

Ask it anything

Questions learners ask about Gravitation and orbits

  • Why don't satellites fall back to Earth?
  • Is there really zero gravity on the space station?
  • How does orbital speed depend on height above Earth?

Any of these, or your own, typed or spoken. The tutor answers on the picture and adapts to how well you are following.

Questions

Asked, Answered

Can LetMeTeach explain Gravitation and orbits?

Yes. Ask in your own words and the tutor plans a lesson on Gravitation and orbits: it starts with a planet with a cannonball fired from a mountain at increasing speeds, each trajectory curving further until one circles the planet completely as an orbit. Then it explains each step out loud as the picture builds, stops when you say "wait, why?", and ends with a checkpoint question.

Where does Gravitation and orbits come up?

Class 9 and 11 CBSE, GCSE and A-level, IB Physics, AP Physics 1 and C, JEE and NEET. The lesson is pitched to your level and the exam or curriculum you follow, and you can upload your own notes or past papers so it uses your textbook's terms.

Can I learn Gravitation and orbits in my own language?

Yes. LetMeTeach teaches in 26 languages and plans the lesson in the language you choose rather than translating an English one, so the terms match what your textbook says. The Free plan includes 7 hours a month with no card.
