How easy was it to use our calculator? Did you face any problem, tell us!

This kinetic energy calculator helps you to calculate kinetic energy that possesses due to the motion or movement of any object.

Also, ours KE calculator uses a simple kinetic energy equation to calculate both the linear and rotational kinetic energy (KE) of a body.

What is Kinetic Energy (KE)?

According to the definition of physics, the energy that is possessed due to motion or movement of any object is kinetic energy. If the object is at rest and we apply some force on it while pushing,it will start moving.

This movement will bring kinetic energy. Therefore, it can be defined as the work required to move a body of a given mass from rest to its stated velocity.

What is Kinetic Energy Formula?

The formula for kinetic energy describes the association between the mass of an object and its velocity. The kinetic energy equation is:

KE = 0.5 * m * v² or K.E. = ½ * m * v²

where:

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

With the help of this formula, it can be estimated how much energy will be needed to move the object of a particular mass. The same amount of energy will be required to decelerate or stop the object, but keep in mind that velocity is squared.

How Our Kinetic Energy Calculator Works

Chose the option “linear” from the drop-down menu of the ke calculator. It follows the following equation:

Linear KE: = 1/2 (M * (V * V))

Input

  • First of all, enter the value of mass
  • Very next enter the value of the velocity
  • Hit the calculate button

Output

  • The very first output will be the value of KE in joules
  • Mass will be delivered the same as the input with a standard unit that is kg
  • Velocity will be delivered the same as the input with a standard unit that m/s
  • To make another calculation just hit the recalculate button

To Calculate Mass:

If you have the value of KE and velocity, then mass can be calculated as follow:

M = KE / (V * V)

Input

  • First of all, enter the value of KE
  • Very next enter the value of the velocity
  • Hit the calculate button

Output

  • The very first output will be the value of KE in joules the same as the input.
  • Mass will be delivered as the second output with a standard unit that is kg
  • Velocity will be delivered the same as the input with a standard unit that m/s
  • To make another calculation just hit the recalculate button

To Calculate Velocity

If you have the value of KE and mass, then velocity can be calculated by this tool as follow:

V = KE / (1/2 * M)

Input

  • First of all, enter the value of KE.
  • Very next enter the value of mass.
  • Hit the calculate button

Output

  • The very first output will be the value of KE in joules the same as the input.
  • Mass will be delivered the same as the input with a standard unit that is kg
  • Velocity will be delivered as the last output with a standard unit that m/s
  • To make another calculation just hit the recalculate button

To Calculate Rotational Kinetic Energy:

From drop-down menu chose “rotational”. This kinetic energy calculator follows the following formula of rotational KE:

KE(rotational)=1/2Iω2

Input

  • Very first you have to Enter the value of the moment of inertia
  • Now Enter the value of the angular velocity
  • Hit the calculate button

Output

  • You will get the value for rotational KE in joules as a standard unit.
  • Moment of inertia will be delivered the same as the input in kg.m² as a standard unit.
  • Value of angular velocity will be delivered same as the input in rad/s as a standard unit.
  • To make another calculation just hit the recalculate button.

To Calculate The Moment of Inertia:

If you have the values for rotational KE and angular velocity the moment of inertia can be computed as follows:

Input

  • Enter the rotational KE
  • Enter the angular velocity
  • Hit the calculate button

Output

  • You will have a value of rotational KE same as the input in joules.
  • You will have the value of the moment of inertia as a required output in kg.m².
  • You will have the value of angular velocity same as the input in rad/s.
  • To make another calculation just hit the recalculate button.

To Calculate The Angular Velocity:

If vales of rotational KE and moment of inertia is known, then angular velocity can find out as follow:

Input

  • Enter the value of rotational KE
  • Enter the value of the moment of inertia
  • Hit the calculate button

Output

  • You will have a value of KE same as the input in joules.
  • You will have a moment of inertia the same as the input in kg.m².
  • You will have a value of angular velocity as the desired output in rad/s.
  • To make another calculation hit the recalculate button
