This problem concerns the properties of circular orbits for a satellite of mass m orbiting a planet of mass m in an almost circular orbit of radius r. in doing this problem, you are to assume that the planet has an atmosphere that causes a small drag due to air resistance. "small" means that there is little change during each orbit so that the orbit remains nearly circular, but the radius can change slowly with time. the following question will ask about the net effects of drag and gravity on the satellite's motion, under the assumption that the satellite's orbit stays nearly circular. use g if necessary for the universal gravitational constant. consider the work done on the system a. increase b. decrease c. stay the same d. vary in a more complex way than is listed here

it becomes positively charged by charging it

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.

given values:

mass = 0.3 kg.

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
