ifferent Kinds of Forces: weight, normal force, frictional force, applied (push, pull) force, tension (strings or cables) Flashcards
(4 cards)
Define weight Fg
Fg is the gravitational force the Earth exerts on any object on or near its surface.
Weight is a vector quantity and is dependent on the local gravitational field strength.
Define normal force FN
FN is the perpendicular force exerted by a surface on an object in contact with it.
The normal force acts perpendicular to the contact surface.
Define frictional force Ff
Ff is the force that opposes the motion of an object.
Frictional force can vary based on the surfaces in contact and the normal force.
How does the frictional force act in relation to the surface?
The frictional force acts parallel to the surface with which the object is in contact.
This characteristic is essential for understanding the mechanics of motion and resistance.
