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.
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.
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:
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.
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
Output
If you have the value of KE and velocity, then mass can be calculated as follow:
M = KE / (V * V)
Input
Output
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
Output
From drop-down menu chose “rotational”. This kinetic energy calculator follows the following formula of rotational KE:
KE(rotational)=1/2Iω2
Input
Output
If you have the values for rotational KE and angular velocity the moment of inertia can be computed as follows:
Input
Output
If vales of rotational KE and moment of inertia is known, then angular velocity can find out as follow:
Input
Output
