AP Physics B: Momentum/Torque/Rotational Motion - Terms
change in momentum (vector) (Unit: Kg m/s)
inertia in motion (vector)
Conservation of Momentum
In the absence of an outside force, the total momentum will be conserved.
Momntum is conserved but Kinetic Energy is not (usually lost) [majority - STICK]
Momentum and Kinetic Energy are both conserved [minority - DONT STICK]
An object's resistance to a change in rotation; the farther the mass is from the rotation point, the greater RI
"rotational equivalent of force"; a force applied so as to cause an angular acceleration
sum of all forces acting on an object is zero
sum of all torques acting on an object is zero
object at rest
Center of Mass
an object balances when it is supported at its center of mass
