any push or pull

attractive force between one "piece" of matter and all other "pieces" of matter

an object's resistance to a change in its motion

two materials rubbing against each other

gravity and electromagnetism

Name two forces that "act at a distance"

electromagnetism

a force that can attract or repel

the force an object exerts perpendicular to its surface (i.e. floor up on your feet)

the force many of my students exert on their science teacher!! :)

force, mass, acceleration

Newton's Second Law of Motion describes how these three properties are related

Does the strength of forces that "act at a distance" get stronger or weaker the farther you move from the objects?

True or false: An object's gravity is stronger the more massive the object.

True or false: If gravity suddenly vanished, a book on a table would immediately float up and away.

Force extending beyond the object responsible for the force.
