Chapter 6: Force & Motion II Flashcards
What is static friction force?
The friction force that attempts to prevent relative motion between two surfaces in contact. |f(arrowsubsmax)| = μ(subs) * |F(arrowsubn)|
μ(subs), also known as the coefficient of static friction, is…
A dimensionless constant for the two surfaces pressed against one another.
What is kinetic friction force (f(arrowsubk))?
The friction force that acts on each surface when two surfaces slip relative to each other.
What is the magnitude of the force on either surface?
|f(arrowsubk)| = μ(subk) * |F(arrowsubn)|
μ(subk), also known as the coefficient of kinetic friction, is…
A dimensionless constant for the two surfaces moving against one another.
Uniform circular motion (UCM) is…
Constant motion following a circular path.
In UCM, according to Newton’s second law, there must be a ___ on a particle directed towards the ___ of the circle.
Net force; center
The net force in UCM is known as the ___ and will always be a combination of other ‘standard” forces, such as: ___, ___, ___ ___, and ___ ___.
Centripetal force; tension; friction; normal force; gravitational force.
a(subrad) = …
(F(subnetrad))/m = (V^2)/r
