Kinds Of Forces Flashcards
1
Q
Weight
A
the gravitational force the Earth exerts on any object on or near its surface
2
Q
Normal force
A
as the perpendicular force exerted by a surface on an object in contact with it
3
Q
Frictional Force
A
The force that opposes the motion of an object and acts parallel to the surface with which the object is in contact
4
Q
Static Friction
A
Friction between 2 solid objects that are not moving relative to each other
5
Q
Kinetic Friction
A
When 2 objects slide across each other and rub together
6
Q
Free-body diagram
A
Shows object as a dot. Forces are shown as labeled arrows which act away for the dot.
7
Q
Maximum Static Friction
A
Max value of SF before the block begins to slide across a surface. Depends on normal force and coefficient of static friction
