Types of Friction Flashcards
What are the two types of friction?
Static and Kinetic friction.
What is static friction?
It is present when an object is at rest.
What is kinetic friction?
It is present when an object is moving.
To move an object, a force ___ than the maximum possible static friction must be applied.
To move an object, a force greater than the maximum possible static friction must be applied.
Kinetic friction is a ___ force.
Kinetic friction is a resistive force.
Kinetic friction can be three types, what are they?
Sliding, rolling, and air friction.
Sliding friction acts on ___, ___ objects sliding on a surface.
Sliding friction acts on dry, solid objects sliding on a surface.
Rolling friction is ___ than sliding and static friction.
Rolling friction is weaker than sliding and static friction.
