Kinetic energy and momentum

  1. Nov 14, 2012 #1
    If the momentum of a body is increased n times, its kinetic energy increases by how many times?

    Depends on what you did to increase the momentum.

    He does have a point, even though his answer seems a little curt.

    What's the formula for momentum?

    What's the formula for kinetic energy?

    They use the same variables, but which one you change matters. Usually, you're looking at what happens when the velocity changes, but you need to specify which to really answer the question.
