What is the acceleration due to gravity at an altitude of 1.00 x 10^6 above the Earth's surface, given that the radius of the Earth is 6.38 x 10^6 m?Homework Equations
Using g = GMm/r^2
Fc = mv^2/r
The Attempt at a Solution
Fc = mv^2/r
How can I solve this equation if I am missing m and v?
and mass =m. F=m*a=m*(GM/r^2)[/QUOTE]MattHorbacz said:The only force acting upon the object in this example is the force of Earth's gravity. You only need to use the equation F=GMm/r^2...remember F=ma, which means that acceleration=G*M/r^2 and mass =m. F=m*a=m*(GM/r^2)
yes exactly...M in this case is the mass of the earth...it appears that they want you to look it up yourself...it happens to be 5.972*10^24 kggcombina said:If the formula is a= GM/R^2
then i only need the value of M
A circular orbit is the path that an object follows around a larger object, such as a planet or star, where the distance between the two remains constant. It is a type of orbit that has a perfectly circular shape, as opposed to an elliptical orbit which is more oval-shaped.
A circular orbit is a type of orbit with a constant distance between the two objects, while an elliptical orbit has a varying distance between the two objects. Additionally, a circular orbit has a perfectly circular shape, while an elliptical orbit is more oval-shaped.
The size of a circular orbit is determined by the mass of the larger object and the speed of the smaller object. The larger the mass of the object, the larger the orbit will be, and the faster the object is moving, the smaller the orbit will be.
No, objects in a circular orbit cannot collide unless they are affected by outside forces, such as gravitational forces from other objects. This is because their orbits are stable and their paths do not cross.
A circular orbit is beneficial for satellites and spacecraft because it allows them to maintain a constant distance from the Earth, which is necessary for communication and data collection. It also requires less energy to maintain a circular orbit compared to an elliptical orbit.
