Strand 3.3: FORCE AFFECTS MOTION

Forces act on objects and have both a strength and a direction. An object at rest typically has multiple forces acting on it, but they are balanced, resulting in a zero net force on the object. Forces that are unbalanced can cause changes in an object's speed or direction of motion. The patterns of an object's motion in various situations can be observed, measured, and used to predict future motion. Forces are exerted when objects come in contact with each other; however, some forces can act on objects that are not in contact. The gravitational force of Earth, acting on an object near Earth's surface, pulls that object toward the planet's center. Electric and magnetic forces between a pair of objects can act at a distance. The strength of these non-contact forces depends on the properties of the objects and the distance between the objects.

• 3rd Grade OER Science Textbook for Utah SEEd Standards
  The Utah Science Open Educational Resources (OER) textbook project was started to bring Utah teachers together to create a resource that aligns to Utah core science standards. The Utah Science OER textbooks are not intended to be curriculum as they do not include labs, assessments, or a teacher guide with answers. They are intended as a reference material for students with content to support teachers classroom instruction and help make sense of science concepts found in standards. This OER textbook is also available in other languages at https://www.uen.org/oer/index.shtml.
