# If the Speed of a Particle is Increased Four Times, How Will Its Kinetic Energy Be Affected? - Physics

Numerical
If the speed of a particle is increased four times, how will its kinetic energy be affected?

#### Solution

K.E, K = 1/2 mv²

if speed is incresed four times

K.E,K' = 1/2 m(4v)²

or K' = 16 x 1/2` mv² = 16K

thus K.E becomes sisxteen times

Is there an error in this question or solution?
