Name two forces that "act at a distance"
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.
