Normal Force Flashcards
Definition of Symmetry
A balanced and proportionate similarity that is found in two halves of an object
What is an interaction pair
Two forces that are in opposite directions, and have equal
magnitudes, and act on different objects.
What is Newton’s third law
States that all forces come in pairs and that the two forces are
equal in strength, opposite in direction, and act on different objects.
Definition of tension
A force along the length of a medium, especially a force carried by a flexible medium, such as a rope or cable
What is the normal force?
The normal force is the perpendicular contact force exerted by a surface on another
object.
The normal force is not always equal to the object’s weight.
Finding the normal force is important when calculating the effects of friction.
