UP:SC15.8.9
Vocabulary
- Sir Isaac Newton
- Newton's Second Law of Motion
- Mass
- Acceleration
- Potential energy
- Kinetic energy
- Force
- External force
- Sum
- Motion
Knowledge
Students know:
- The acceleration of an object is determined by the sum of the forces acting on it; if the total force on the object is not zero, its motion will change.
- The greater the mass of the object, the greater the force needed to achieve the same change in motion.
- For any given object, a larger force causes a larger change in motion. Force = mass x acceleration; F=ma.
Skills
Students are able to:
- Demonstrate Newton's second law.
- Articulate a statement that relates a given phenomenon to a scientific idea, including Newton's second law and the motion of an object.
Understanding
Students understand that:
- Newton's Second Law states that changes in an object's motion depends on the sum of the external forces on the object and the mass of the object.
