Calculating centripetal acceleration between moon and satelite

In summary, the conversation discusses the relationship between force, acceleration, and distance in a centripetal force scenario. The equation F=gMm/r^2 is used to calculate force, not acceleration, but it can be rearranged to find acceleration. The conversation also suggests considering how acceleration varies with distance in solving a specific problem.

Not quite, but you are on the right track. [tex] GMm/r^2 [/tex] is a measure of force. Technically to find the acceleration, set it equal to ma and, solve for a. Then, to solve your original problem, note how a varies with r.
 

Related to Calculating centripetal acceleration between moon and satelite

1. How is centripetal acceleration calculated between the moon and a satellite?

Centripetal acceleration is calculated using the formula a = v^2/r, where a is the centripetal acceleration, v is the velocity of the satellite, and r is the distance between the satellite and the center of the moon.

2. What units are used to measure centripetal acceleration?

Centripetal acceleration is typically measured in meters per second squared (m/s^2).

3. How does the mass of the satellite affect the centripetal acceleration?

The mass of the satellite does not affect the centripetal acceleration. Only the velocity and distance from the center of the moon play a role in the calculation.

4. What is the relationship between centripetal acceleration and centripetal force?

Centripetal acceleration and centripetal force are directly proportional to each other. This means that as the centripetal acceleration increases, so does the centripetal force required to maintain the circular motion of the satellite around the moon.

5. How does the distance between the moon and the satellite affect the centripetal acceleration?

The distance between the moon and the satellite has an inverse relationship with the centripetal acceleration. This means that as the distance increases, the centripetal acceleration decreases.
