What do you know about circular motion? In particular, about centripetal acceleration?

The Attempt at a Solution



Proof was asked from me. How do i proof it.

In "w^2 sub. uydu", uydu means satellite.

Use Newton's 2nd Law. Equate the gravitational force on the satellite to the product of the satellite's mass times its centripetal acceleration.

1. What is the proof of angular speed of a satellite?

The proof of angular speed of a satellite is based on the fundamental laws of physics, specifically Kepler's laws of planetary motion. It involves calculating the angular velocity of the satellite by measuring its orbital period and distance from the object it is orbiting.

2. How is the angular speed of a satellite measured?

The angular speed of a satellite is measured using a combination of astronomical observations and mathematical calculations. Astronomical observations involve tracking the satellite's position and velocity in relation to the object it is orbiting. Mathematical calculations then use this data to determine the angular speed.

3. What factors affect the angular speed of a satellite?

The angular speed of a satellite is affected by several factors, including its distance from the object it is orbiting, the mass of the object it is orbiting, and any external forces acting on the satellite such as gravitational pull from other objects.

4. Why is the proof of angular speed important in satellite orbits?

The proof of angular speed is important in satellite orbits because it allows us to accurately predict and track the movement of satellites in orbit. This information is crucial for satellite communication, navigation, and other applications that rely on precise satellite positioning.

5. Can the angular speed of a satellite change over time?

Yes, the angular speed of a satellite can change over time due to a number of factors such as changes in the object it is orbiting, external forces, and atmospheric drag. However, these changes can be predicted and accounted for in the calculations used to determine the angular speed.
