Steps for Kinetic Energy Calculator

Back to Top
Step 1 :  

Kinetic energy is defined as the energy possessed by an object by virtue of its motion.



Step 2 :  

Formula:


K.E = 1/2 * mv2. Joules


State the equation you plan to use and plug in the values.

  1. Given that the displacement of body in meters is a function of time as follows : x = 3t2+ 6.The mass of the body is 4 kg.What is the increase in its kinetic energy two second after start of the motion ?


    Step 1 :  

    Velocity v=dx/dt=d/dx (2t2+ 6) =4t.


    After two second the velocity is 4(2) = 8 m/s.



    Step 2 :  

    Formula:


    K.E = 1/2 * mv2. Joules


    Where m = 4 kg and v = 8 m/s.


    K.E = 1/2 * 4 *82.



    Answer  :  

    K.E = 128 Joules.



  2. The displacement of body,whose velocity is 3 m/s .The mass of the body is 4 kg.What is the kinetic energy of the motion ?


    Step 1 :  

    Formula:


    K.E = 1/2 * mv2. Joules


    Where  m = 4 kg and v = 3 m/s.



    Step 2 :  

    Plug in the values in the above equation.


    K.E = 1/2 * 4 *32.



    Answer  :  

    K.E = 32 Joules.
