Concept explainers
An orbiting satellite of mass m is pulled toward Earth by a force ma. Equate ma to the force in Newton’s equation for universal gravitation and show that the satellite’s acceleration is a
To show:The acceleration of the satellite is
Explanation of Solution
Given:
Mass of orbiting satellite is m .
Satellite is pulled towards Earth by a force equal to ma .
Formula used:
The Newton’s equation for gravitational force is,
Here,
Calculation:
The expression for the gravitation force acting on the satellite is,
As per Newton’s Second Law of Motion,
To find the acceleration of the satellite, equate equation (1) and (2).
Conclusion:
Thus, the acceleration of the satellite is shown as
