Kinetic Energy Calculator
If you want to evaluate the energy of motion in an object, you can use our kinetic energy calculator.
The energy an object posses due to its motion is known as kinetic energy. The SI unit used for kinetic energy is Joule (J). It's the force required by an object to accelerate from its initial to its final velocity. Moreover, an entity/object will sustain its kinetic energy, gained from the acceleration, until variation in speed.

Formula of Kinetic Energy Calculator
If you want to find kinetic energy in an object, you can use our calculator, or to find it by yourself, you can use the KE equation listed below:
KE = 0.5 * m * v²
Where,
m = mass
v = velocity
3 values are known to us and 1 value is unknown. e.g., D/10 = 15/5.

Example
For more precise understanding of concepts, let us have an example below:
Suppose a bullet has a mass of 5g, moving at the speed of 1 km/s, what will be the kinetic energy of a bullet?
Given data
Mass = 5g =0.005 kg
Speed = 1 km/s = 1000 m/s
To Find
Kinetic energy = ?
Solution
To find the kinetic energy of the bullet, you can use the formula listed below:
KE = 0.5 * m * v²
Putting values in the formula:
Kinetic energy = 0.5 * 0.005 * (1000)² = 2500 J
