defined as the tendency of an object at rest
to remain at rest and an object in motion to stay
moving in a straight line at a constant velocity.
Inertia
defined as the property of a rotating body to resist
change in its state of rotation.
moment of inertia
the symmetry pf axis of any shape except a pole (end) is always
in the center
distance from an axis of rotation where the mass of a
body may be assumed to be concentrated without altering
the moment of inertia of the body about that axis
radius of gyration (K)
is the twisting force that tends to cause
rotation
TORQUE
CCW RIGHT TO LEFT (UP TO DOWN)
+
CW LEFT TO RIGHT(UP TO DOWN)
-
A motion of an object around a circular path, in a
fixed orbit.
* Also called angular motion.
Rotational MotioN
rate of change of angular displacement. It
tells us how fast an object is rotating and the axis
about which it rotates.
Angular Velocity (ω)
rate of change of angular velocity. It tells us
how the rotation is speeding up or slowing down
Angular Acceleration (α
defined as a body at rest having zero acceleration
and zero net force
Static EquilibriuM
how hard it is to stop an object from
rotating.
Angular Momentum
