Which of the following statements are true? Because the Earth has mass it produces gravity. There is no gravity at the space station I need to do work to move a satellite from lower to higher orbit. Because the force of gravity is a conservative force and because it acts as a centripetal force it does no work, the mechanical energy of Earth is conserved and it will not crush into the Sun. Since Moon has no air, there is...

The energy of motion is called: Kinetic energy. potential energy, inertial energy. Power. In an inelastic collision: momentum is conserved. kinetic energy is conserved, both (a) and (b). If the velocity of a moving object is doubled and its mass is cut in half, the kinetic energy of the object is; remains the same, doubled quadrupled, cut in half. When the net work done on an object is speed of the object is me on an object is zero; the...

А D z Problem 3. Work done by gravity and change in gravitational potential energy In problem the box was moving in a horizontal direction, and therefore no work was done by gravity. Here, we will analyze a situation where the force of gravity has some component that points along the direction of the displacement, and therefore there is non-zero work done by gravity on the system of interest Consider a box of mass 10 kg, initially at rest, which...

Select all of the following statements that are true about potential energy and conservative forces. Potential energy is the energy associated with the configuration of a system. It is only possible to have potential energy if there are 2 or more objects in the system that interact with each other through internal, conservative forces. Absolute values of potential energy have no meaning: only changes in the potential energy are physically meaningful. There is only one kind of potential energy: gravitational...
