AP Physics B: Momentum/Torque/Rotational Motion - Terms

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