ifferent Kinds of Forces: weight, normal force, frictional force, applied (push, pull) force, tension (strings or cables) Flashcards
(4 cards)
1
Q
Define weight Fg
A
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.
2
Q
Define normal force FN
A
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.
3
Q
Define frictional force Ff
A
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.
4
Q
How does the frictional force act in relation to the surface?
A
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.
