A system of objects may also contain stored (potential) energy, depending on their relative positions.

EG016003	The gravitational potential energy of an object depends on the mass of the object and the object's distance from the center of the earth.
EG071002	Two pictures that weigh the same and are hung the same height above the floor have the same amount of gravitational potential energy.
EG022003	A person will have the same amount of gravitational potential energy at the top of a mountain regardless of the path the person takes to get there.
EG013004	When a coconut falls from a tree, it has the most gravitational potential energy at its highest point above the ground.
EG088001	When two children who weigh the same are on a teeter-totter, the child who is up has more gravitational potential energy than the child who is down.
EG015003	The mass of a rock will affect the gravitational potential energy of a rock on top of a cliff.
EG018004	For two books on a table, the book that weighs more has more gravitational potential energy.
EG020003	For two objects that are the same distance from the center of the earth, the object with more gravitational potential energy weighs more.
EG090001	Two identical balls that are thrown up in the air will have the same amount of gravitational potential energy when they are at the same height above the ground.
EG093001	The gravitational potential energy of an object depends on the object’s distance from the center of the earth but not the speed of the object.

Items associated with this NGSS statement in this project (Original Project) and other key ideas
EG036004	The elastic energy of an object that is being stretched depends on how much the object is stretched and how difficult it is to stretch it.
EG086001	The elastic energy of an object that is being compressed depends on how much the object is compressed and how difficult it is to compress it.
EG042003	A spring has elastic energy when it is stretched and when it is compressed.
EG035004	The elastic energy of a spring increases when a student compresses it.
EG041003	For two identical rubber bands, the rubber band that is stretched more has more elastic energy.
NG099001	When skateboarding down a hill, gravitational potential energy is transformed into motion energy and thermal energy.
NG049003	When a spring is used to shoot a cart across the floor, the spring transfers energy to the cart. (This item uses bar graphs to illustrate the amount of elastic energy the spring has and the amount of motion energy the cart has as the cart is rolling across the floor.)
