Chapter 2: Newton's Laws of Motion

Question 1

Force Pair

Answer 1

Objects in an interaction that involves action force and reaction force

Question 2

Interaction

Answer 2

A push or a pull; Force

Mutual interaction between objects during which each object exerts and equal and opposite force on the other

Question 3

Law of Inertia/Newtons First Law of Motion

Answer 3

Objects, resistant to change, keep doing whatever they’re already doing

exp.: Objects at rest stay at rest unless an external force acts upon them

Question 4

Acceleration/Newton’s Second Law of Motion

Answer 4

Acceleration and net force are directly proportional AND acceleration and mass are inversely proportional

Question 5

Action & Reaction/Newton’s Third Law of Motion

Answer 5

For every action there is an equal and opposite reaction

Whenever an object exerts a force on a second object, the second object exerts and equal and opposition force on the first object

Question 6

Terminal speed

Answer 6

The speed at which the acceleration of a falling object terminates when air resistance balances its weight.

Terminal speed for various objects based on weight, size, and orientation

Question 7

Terminal velocity

Answer 7

Terminal speed in a given direction (such as downward)
