Physics: Unit 5 - Orbits & Field Forces 17 of 11 A satellite moving in a circular orbit with respect to the Earth's center experiences a gravitiational force. If the satellite is put into a new circular orbit of a smaller
radius, how will the gravitational force and the speed of the satellite change, if at all?

Name three different units of energy used to measure heat and describe what type of situations each is usually used.

Ryan is examining the energy of the particles in a bar of gold. what is ryan most likely studying?

Assume that two of the electrons at the negative terminal have attached themselves to a nearby neutral atom. there is now a negative ion with a charge -2e at this terminal. what are the electric potential and electric potential energy of the negative ion relative to the electron? the electric potential and the electric potential energy are both twice as much. the electric potential is twice as much and the electric potential energy is the same. the electric potential is the same and the electric potential energy is twice as much. the electric potential and the electric potential energy are both the same. the electric potential is the same and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron. the electric potential is twice as much and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron.
