Overview:

Inertia means that an object in motion will stay in motion in the same direction, or will stay at rest, unless another force acts upon it. For an object to change direction or stop moving, something has to overcome inertia.

The classroom resource provides a video that will explain Newton's First Law of Motion. This resource can provide background information for students before they conduct their own demonstrations. There is also a short test that can be used to assess students' understanding.

Content Standard(s):
 Science SC2015 (2015) Grade: 8 Physical Science 8 ) Use Newton's first law to demonstrate and explain that an object is either at rest or moves at a constant velocity unless acted upon by an external force (e.g., model car on a table remaining at rest until pushed). NAEP Framework NAEP Statement:: P8.14a: An object's motion can be described by its speed and the direction in which it is moving. An object's position can be measured and graphed as a function of time. An object's speed can be measured and graphed as a function of time. NAEP Statement:: P8.16a: Forces have magnitude and direction. NAEP Statement:: P8.16b: Forces can be added. NAEP Statement:: P8.16c: The net force on an object is the sum of all the forces acting on the object. NAEP Statement:: P8.16d: A nonzero net force on an object changes the object's motion; that is, the object's speed and/or direction of motion changes. NAEP Statement:: P8.16e: A net force of zero on an object does not change the object's motion; that is, the object remains at rest or continues to move at a constant speed in a straight line. Unpacked Content Scientific And Engineering Practices:Constructing Explanations and Designing SolutionsCrosscutting Concepts: Cause and EffectDisciplinary Core Idea: Motion and Stability: Forces and InteractionsEvidence Of Student Attainment:Students: Demonstrate, using Newton's First Law, that an object is either at rest or moves at a constant velocity unless acted upon by an external force. Explain Newton's First Law.Teacher Vocabulary:Sir Isaac Newton Newton's First Law of Motion Constant velocity Balanced force Unbalanced force External force Rest Motion InertiaKnowledge:Students know: An object at rest remains at rest unless acted on by an external force. An object in motion remains in motion unless acted upon by an external force. Inertia is the tendency of an object to resist a change in motion. An object subjected to balanced forces does not change its motion. An object subjected to unbalanced forces changes its motion over time. Constant velocity indicates that an object is moving in a straight line at a constant speed.Skills:Students are able to: Demonstrate Newton's first law. Articulate a statement that relates a given phenomenon to a scientific idea, including Newton's first law and the motion of an object.Understanding:Students understand that: Newton's First Law states that an object at rest remains at rest unless acted upon by an external force. Newton's First Law states that an object at in motion remains in motion at a constant velocity unless acted upon by an external force.AMSTI Resources:AMSTI Module: Experimenting with Forces and Motion Alabama Alternate Achievement Standards AAS Standard: SCI.AAS.8.8- Compare an object at rest and an object in motion; recognize that an object at rest remains at rest if not acted on by an outside force; demonstrate a method to change an object's motion; identify forces that cause an object in motion to slow down or stop moving.
