Newton's Third Law

Vocabulary flashcards covering Newton's Third Law concepts, contact forces, collisions, gravity, drag, and friction.

Contact Force

Push or pull on one object by another object that is touching it

Newton’s Third Law

Object 1 applies a force on object 2, object 2 applies a force of the same magnitude but in the opposite direction on object 1.

Force Pair

The forces two objects apply on each other; set of two forces that are equal in magnitude and opposite in direction.

Normal Force

Force that pushes back on an object perpendicular to the object’s surface (Fn or Fnorm)

Tension Force

Pulling or stretching force transmitted along an object such a rope or string.

Action Reaction

Forces always come in pairs; Action = Force A applies to B / Reaction = Force B applies to A; one does not cause the other but one cannot exist without the other.

Drag

Fluid resistance that opposes the motion of a body through a liquid or gas.
