Kinetic energy is a form of energy that an object possesses due to its motion. It's a fundamental concept in physics, reflecting the dynamic state of objects which are moving. The amount of kinetic energy an object has depends on its mass and the speed at which it is moving.

How to Calculate Kinetic Energy

Calculating kinetic energy can be done with just a few variables. The variables required for calculation include:

  1. Mass

  2. Velocity
When you have the value of each variable you can then plug them into this formula to calculate the amount of kinetic energy:

  • KE = Kinetic energy

  • M = Mass

  • V = Velocity

Understanding Your Results

Your result will be a number that represents the kinetic energy in your specific situation. This number is displayed in joules.

Calculation Example

We have been wondering how much kinetic energy we generate when we are running. So we decided to use this tool to try and figure it out. We have a mass, or weight, of 165 pounds and can run at a rate of 15 miles per hour. To use this tool we will first enter our weight, 165, into the mass field and choose the pounds (lb) unit from the dropdown menu. Then, we will enter 15 into the velocity field and choose miles per hour (mph) from the dropdown menu. We can now hit calculate and find that we generate a total of 1,682.65 joules of kinetic energy.

Kinetic Energy - Frequently Asked Questions

Since kinetic energy depends on the square of the velocity (v2), even small increases in velocity result in a disproportionately large increase in kinetic energy, compared to changes in mass.

No, kinetic energy cannot be negative. Since it is calculated using the square of the velocity, the result is always a non-negative number.

When an object stops moving, its kinetic energy becomes zero because the velocity is zero. The energy is not lost but is usually converted into other forms of energy, such as heat or potential energy, depending on the situation.

You can use one of our other tools, our Energy Converter, to help you convert your joules into another unit of energy measurement.
