Kinetic energy (Force and d(x))

  1. Mar 5, 2009 #1
    1. The problem statement, all variables and given/known data

    If no energy is dissipated , how much KE does an object gain if
    a) A 10N force is applied for 5m
    b) A 20N force is applied for 2m

    2. Relevant equations



    3. The attempt at a solution
    I know there is work being done if an object moves causing it to have KE. I think work is Force * displacement and the units for Force (N) and displacement (m) works out to Joules. So does that mean I use multiply force and displacement to find the amount of KE gained?
