momentum-and-impulse-with-vectors

Impulse-momentum principle with vectors

How do impulse and momentum work in 2D?

• Impulse and momentum can be used in 2D as they are vector quantities

  • Impulse in 2D essentially works the same way as impulse in 1D

• For a constant force given by the vector  N acting on a particle for  seconds the impulse is given by the vector:

  •  

  • The units are still N s (equivalent to kg m s^-1 )

• For a particle of mass  the impulse is still equal to the change in momentum
