# If I triple the velocity of an object- by how much of a factor did the.docx

If I triple the velocity of an object, by how much of a factor did the kinetic energy increase?
3
6
4
9
Solution
The kinetic energy of an object is given by 1/2*m*v^2.
Where v is velocity and m is mass of the object.
If the velocity is increased to 3v (triple), the kinetic energy becomes 1/2*m*(3v)^2 = 9*(KE) original.
