Gravity
Terms in this set (7)
rotational inertia
the resistance of an object to changes in its rotational motion; depends on the distribution of the mass; the higher it is the more difficult to change the object's rotation
three principal axis of rotation
longitudinal axis, transverse axis, medial axis
acceleration on an incline
objects of the same shape but different sizes accelerate equally on an incline
angular momentum
product of rotational inertia and rotational velocity
angular momentum = rotational inertia (I) x rotational velocity (ω)
angular momentum = m v r
Newton's first law of inertia for rotating systems
an object or system of objects will maintain its angular momentum unless acted upon by an unbalanced external torque
law of conservation of angular momentum
angular momentum is conserved when no net external torque acts on an object
simulated gravity
from within a rotating frame of reference, there seems to be an outwardly directed centrifugal force
