Impulse and Momentum

linear momentum

mass in motion; measures how hard it is to stop a moving object

vector

linear momentum is a ___ quantity

directly proportional

mass and velocity are ___ to momentum

impulse-momentum theorem

alternative version of Newton’s 2nd Law of Motion

impulse

product of force and time; “follow through” in sports

conservation of momentum

if mass and velocity values remain the same the momentum will be constant

law of momentum conservation

in a closed and isolated system, the total momentum of the objects are equal before and after collision

system

collection of objects that affect one another

vector sum

in a system of several bodies, the momentum is the ___ of all the momentum of bodies

change in momentum

equal to the impulse of force it experiences

newton’s 3rd law of motion

law of conservation of momentum is related to

0

if unbalanced force is _ the total momentum is maintained

maintained

the momentum of a system is ___ if it is left alone
