The gravitational potential (V) at a location isthe gravitational potential energy (U) at that location per unit mass: where m is the mass of the object. Potential energy is equal (in magnitude, but negative) to the work done by the gravitational field moving a body to its given position...
1. Give one example of low gravitational potential energy 2. Give one example of high gravitational potential energy What is the difference between kinetic and gravitational potential energy? What happens to gravitational potential energy when an object travels downwards? To what form of...
so it describes the amount of energy exerted per unit of charge. We can also describe small amounts of energy (often stored as electric potential energy) through a units called the electron volt (eV). This units is one volt multiplied by the charge of an electron, equivalent to 1.602 x ...
Energy is the ability to do work. There are different types of energy, such as kinetic energy, potential energy, light energy, or thermal energy. These types of energy can be interconverted but are not created or destroyed. Answer and Explanation:1 ...
a. Find the ratio of the electrostatic force to the gravitational force between two electrons. b. Will this ratio change if the two electrons are replaced by protons? If yes, find the new ratio. Two charged spheres 10 cm apart attrac...
The need for energy has been growing over the years. This has been particularly true for developing countries. If we look at the world’s demand for energy, we will find that it has tripled in the past 50 years. While much of this demand is said to be put forward by the rapidly boo...
and find that the gravitational force on the system is just Mg, where gis the gravitational acceleration and Mis the total mass of the system, consisting of the mass of the plates renormalized by the Casimir energy of each plate separately, plus the energy of the Casimir interaction between ...

The energy you use isn't lost, but stored by your body as gravitational potential energy, which you could use to do other things (whizzing down a slide back to ground level, for example).What you do when you climb steps, ladders, mountains, or anything else is work against Earth's ...
a. Find the ratio of the electrostatic force to the gravitational force between two electrons. b. Will this ratio change if the two electrons are replaced by protons? If yes, find the new ratio. List two graphical techniques that can be used to ...
