Vocabulary
- Sir Isaac Newton
- Newton's First Law of Motion
- Constant velocity
- Balanced force
- Unbalanced force
- External force
- Rest
- Motion
- Inertia
Knowledge
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.
