, 10.1.11 Describe friction
A force that acts parallel to the interface of
two surfaces that are in contact, and opposes
their relative motion .
10.1.21 Describe the coefficient of friction
4 =
E) A dimensionless scalar
quantity which is the
ratio of the force of friction Ff ,
between two
bodies and the normal reaction force ,
R .
10.1.3 -
Distinguish between the coefficient of
static friction and dynamic friction
static friction
↳ when force applied
a is to move a
stationary
object over another surface
↳ at some point the force applied
,
is sufficient
to overcome the static friction .
Dynamic friction
↳ once the object is in motion
↳ coefficient of
dynamic friction is
usually
lower than the coefficient of static friction .
