Learning Objectives

-Define Newton’s third law qualitatively and mathematically.

-Present examples of equal-and-opposite force action-reaction pairs.

-Introduce frames of reference and demonstrate their importance for understanding Newton’s third law.

-Clarify ways to think about systems of objects - either individually or in groups.

Vocabulary

action-reaction pairs - pairs of objects in which one object exerts a force, known as the action, on another object, and the other object reacts to that action in a way in which the force is equal in magnitude but opposite in direction.

Newton’s 3rd Law of Motion - for every action there is an equal and opposite reaction.

Georgia Standards of Excellence

SP2
Obtain, evaluate, and communicate information about how forces affect the motion of objects.
a
Construct an explanation based on evidence using Newton’s Laws of how forces affect the acceleration of a body. • Explain and predict the motion of a body in absence of a force and when forces are applied using Newton’s 1st Law (principle of inertia). • Calculate the acceleration for an object using Newton’s 2nd Law, including situations where multiple forces act together. • Identify the pair of equal and opposite forces between two interacting bodies and relate their magnitudes and directions using Newton’s 3rd Law.
