Help physic to calculate btw satellite and earth

Click For Summary
SUMMARY

The discussion focuses on calculating the altitude at which a satellite must be placed for its orbital velocity to match the Earth's rotation rate. Key parameters include the Earth's radius of 6,380 km and its mass of 5.98 x 1024 kg. The term "Orbital Velocity" is emphasized as the correct concept for this calculation. Participants are encouraged to show their working and attempt the problem before seeking assistance.

PREREQUISITES
  • Understanding of orbital mechanics
  • Familiarity with gravitational equations
  • Knowledge of angular velocity concepts
  • Basic algebra for solving equations
NEXT STEPS
  • Research "Orbital Velocity calculations" using the formula V = √(GM/r)
  • Study "Gravitational force equations" to understand satellite placement
  • Learn about "Geostationary orbits" and their characteristics
  • Explore "Physics of satellite motion" for deeper insights
USEFUL FOR

Students in physics, aerospace engineers, and anyone interested in satellite dynamics and orbital mechanics.

the angular velocity of the satellite to be equal to the rotation rate of the earth.given that the radius of the Earth is 6380km and the mass Earth 5.98 * 10^24.how high the surface of Earth should satellite be placed

Hello lovelycecila!

It seems from the date you provided, and what result you want, that what you meant was "Orbital Velocity" rather than "angular velocity" .

On PF it is required that you show us some working and a reasonable attempt before we can offer any real help. We don't do the homework for you, after all. Think perhaps of some relevant equations, that should definitely help.
