The kinetic energy calculator with solution calculates the kinetic energy that is possessed due to the motion or movement of any object. 

Kinetic Energy (KE):

“The change in kinetic energy is possessed due to the motion or movement of any object.”

Therefore, it can be defined as the work required to move a body of a given mass from rest to its stated velocity.

Kinetic Energy Formula:

The kinetic energy formula describes the association between the mass of an object and its velocity.  The kinetic energy equation is: $$KE = \dfrac{1}{2}mv^2$$

Where:

  • m is repressing the mass of any object
  • v represents the velocity of the object.

The maximum Kinetic Energy Calculator utilizes the formula KE = (1/2)mv2, the KE equals one-half of the mass (m) times velocity squared (v2). 

Find M, Given KE and V:

  • Calculate "m" given Kinetic energy and "v"
  • Mass m equals 2 times kinetic energy divided by velocity squared v2
  • The kinetic and potential energy are interconvertible to each other 

$$m = \dfrac{2KE}{v^2}$$

Find V, Given KE and m:

  • Calculate "v" given Kinetic energy and "m"
  • Velocity v equals the square root of KE divided by one-half of the "m"
  • Initial and final Kinetic energy are different due to the position and velocity of an object $$v = \sqrt{\dfrac{KE}{\frac{1}{2}m}}$$

How to Calculate Rotational Kinetic Energy?

The formula for the rotational KE is as follows:

 KE(rotational)=1/2Iω2

Enter the Moment of "Inertia" and "Angular Velocity" in the rotational kinetic energy calculator to calculate the KE of rational objects.

Example:

Find the KE of the mass of 23 kg and velocity of 23 meters per second. Then what is the Kinetic energy of the object?

Given:

Mass = 23 kg

Velocity = 23 meters per second

Kinetic energy =?

Solution:

K.E = 1/2*m*v2

K.E= 1/2*23*23^2

K.E= 6083.5 joule
