**Kinetic Energy Calculator:** Need help to find Kinetic Energy? Use this simple Kinetic Energy Calculator tool to get answers easily in seconds. We will give you everything in this calculator along with some units. Just you have to enter parameters and click calculate. Still, we have provided kinetic energy definition, formulas, examples below. Check it out.

According to Physics, Kinetic Energy is defined as the energy that is possessed due to motion or movement. Kinetic energy depends on mass and velocity. If the object is at a rest position then we apply some force on it, then it starts moving. That movement we call Kinetic Energy. The unit of Kinetic Energy is the joule( J) because energy is a scalar quantity.

Kinetic Energy = 0.5 * mass * square of velocity.

Here, we will know the step by step process to find Kinetic Energy. They are explained below

- First, you need to enter two known values into the boxes.
- Leave that empty box that is unknown and then click “Calculate”.
- You will be able to see the answer in the output field.
- In the same way, you can calculate mass and velocity.

Kinetic Energy of the body is one-half of the product of the mass of the body and the square of its speed. We will see the formula in detail.

**K.E = 0.5 * m * v ^{2} (or) ½ * m * v^{2}.**

Where,

K.E is the Kinetic Energy M is the mass of the body V is the velocityRearranging the Kinetic Energy Formula we can find the other parameters like mass and velocity as follows

- If they were given K.E and velocity you need to find Mass with the formula

M = 2k / v^{2}

- If they were given K.E and mass of the body you need to find velocity with the formula

V = √ 2k/m

**Question 1: Calculate the Kinetic Energy of the object that has a mass of 30kg and velocity of 5m/s?**

**Solution:**

Given Parameters,

m= 30kg, v = 5m/s, K.E =?

Formula,

K.E = ½ * m * v^{2}

Substitute the values,

K.E = ½ * 30 * 52 = 375 Joules.

**Question 2: Calculate the mass of an object having Kinetic Energy is 20J, and the velocity is 3m/s?**

**Solution:**

Given Parameters,

m= ?, v = 3m/s, K.E =10j

Formula,

K.E = ½ * m * v^{2}

Rearrange this Formula,

m= 2k/v2

K.E = 2*10/ 32 = 2.2 kg

**Question 3: Calculate the velocity of an object having a mass is 3kg and Kinetic Energy is 10 J?**

**Solution:**

Given Parameters,

m= 3 kg, v = ?, K.E =10 j

Formula,

K.E = ½ * m * v^{2}

Rearrange this Formula,

v= √2k/m

K.E = = √2*10/3 = √20/3 = 2.58 m/s
