Knowledge and Skills Statement

Force, motion, and energy. The student knows the nature of forces and their role in systems that experience stability or change.

force acting on an object such as pushes and pulls

a force that opposes relative motion between systems in contact

a physical phenomenon where masses exert a pull on each other from a distance; the objects are pulled toward each other's center of mass

a physical phenomenon that includes the attraction between iron and a magnet, is exhibited by both magnets and electric currents and is a type of energy characterized by fields of force

the force that a surface applies to an object that it is in contact with, preventing the object from passing through the surface; acts perpendicular to the surface on which the object rests and is equal in magnitude to the force of the object on the surface

regularly interacting or interdependent group of items forming a unified whole

Summary: Beginning with uncovering misconceptions, this article dives into four forces: friction, gravity, push/pull, and magnetism, and how they can be explored using everyday objects.
