momentum and impulse

quiz 11/18/16

QuestionAnswer
conservation of momentum the total momentum remains constant unless a net external force acts on a system
momentum product of the measure and velocity of an object
what is momentum measured in? expressed in "newton seconds" (Ns)
impulse the quantity of force and time applied in a situation
spring compressible, helical structure that returns to its uncompressed state upon release
momentum is also a measure of what? an object's resistence to outside forces
forces move- or else they wouldn't be forces
for KE= .5mv^2, doubling the velocity will have the same impact as quadrupling the mass
mass and velocity in KE=.5mv^2 are inversely proportional
for any 2 objects colliding, the net kinetic energy before... will equal the net KE after impact
momentum increases... when either mass or velocity increases
force is... expressed in newtons N=kg(m)/s^2
momentum formula p=mv
