Questions/
Specificity
Guiding Questions:
Unit 8.6(C) investigate and
describe applications of Newton's
law of inertia, law of force and
acceleration, and law of actionreaction such as in vehicle
restraints, sports activities,
amusement park rides, Earth's
tectonic activities, and rocket
launches.
EOC READINESS
What are everyday
examples of Newton’s 3
Laws?
Specificity:
Teach to find all variables
in Force = mass x
acceleration
1st law: if all the forces
acting on an object are
balanced, the object will
continue in its state of
motion(straight line,
constant speed)
It is important for students
to understand the
interactive nature of forces
(3rd law) and the predictive
ability of 1st law and 2nd
law. It isn’t necessary for
them to memorize the laws.
