Unit Essential Question:
How do scientists use forces and Newton’s Laws to describe the motion of objects?
Concept: Newton’s First and Second
Laws
Concept: Newton’s Third Law of
Motion and Momentum
Concept: Universal
Forces
3.2.10.B1.- Analyze the relationships among the net
forces acting on a body, the mass of the body, and
the resulting acceleration using Newton’s Second
Law of Motion.
3.2.P.B1.- Use force and mass to explain
translational motion or simple harmonic motion of
objects.
3.2.10.B6.- Explain how the behavior of matter and
energy follow predictable patterns that are defined
by laws.
3.2.P.B6.- Use Newton’s laws of motion and
gravitation to describe and predict the motion of
objects ranging from atoms to the galaxies.
3.2.12.B6.- Compare and contrast motions of objects
using forces and conservation laws.
3.2.10.B1.- Use Newton’s Third Law to
explain forces as interactions between
bodies.
3.2.10.B1.- Describe how interactions
between objects conserve momentum.
3.2.10.B6.- Explain how the behavior of
matter and energy follow predictable
patterns that are defined by laws.
3.2.P.B6.- Use Newton’s laws of motion
and gravitation to describe and predict the
motion of objects ranging from atoms to the
galaxies.
3.2.12.B6.- Compare and contrast motions
of objects using forces and conservation
laws.
3.2.10.B1.- Apply Newton’s
Law of Universal
Gravitation to the forces
between two objects.
3.2.P.B6.- Use Newton’s
laws of motion and
gravitation to describe and
predict the motion of objects
ranging from atoms to the
galaxies.
3.2.12.B6.- Compare and
contrast motions of objects
using forces and
conservation laws.
