how is total mechanical energy expressed?
Give this one a try later!
E=K+U
vectors may be added either ______ or ______.
,Give this one a try later!
graphically; analytically
how is the coefficient of static friction different from the coefficient of kinetic friction?
Give this one a try later!
the coefficient of static friction is the threshold of motion. its the
amount of force it takes to get an object in motion. the coefficient of
kinetic friction is the amount of force it takes to keep an object in
motion
this force keeps two surfaces "stuck together"
Give this one a try later!
static friction
the amount f energy needed to move a weight/force of 1 Newton through a distance
of 1 meter
Give this one a try later!
joule
, how is potential energy expressed?
Give this one a try later!
U = mgh
what is the experimental method of finding the equilibrant vector?
Give this one a try later!
- there are 2 forces applied to a force table
- experimentally find the resultant force by finding the angle and
mass necessary to balance the 2
- the equilibrant vector will be the same magnitude but opposite
direction of there resultant force
the angular velocity of a rolling sphere that is not slipping is the ______ of a point on the
circumference, divided by the ______ of the sphere.
Give this one a try later!
velocity; radius
a type of energy that depends on the mass of he objet, the acceleration due to
gravity, and its location
