Understanding the increase in kinetic energy of an object is crucial in physics and engineering. The kinetic energy of an object depends on its mass and velocity. When an object’s velocity changes, its kinetic energy changes accordingly. This article explains how to calculate the increase in kinetic energy using a simple formula and a handy calculator.

## Formula

The increase in kinetic energy (ΔKE\Delta KEΔKE) can be calculated using the formula:

ΔKE=0.5×m×v2\Delta KE = 0.5 \times m \times v^2ΔKE=0.5×m×v2

where:

- ΔKE\Delta KEΔKE is the increase in kinetic energy (Joules)
- mmm is the mass (kg)
- vvv is the velocity (m/s)

## How to Use

To use the Energy Increase Calculator:

- Enter the mass of the object in kilograms.
- Enter the velocity of the object in meters per second.
- Click the “Calculate” button.
- The increase in kinetic energy will be displayed in joules.

## Example

Suppose we have an object with a mass of 10 kg and a velocity of 5 m/s. Using the calculator:

- Enter 10 in the mass field.
- Enter 5 in the velocity field.
- Click “Calculate.”
- The increase in kinetic energy is calculated as 125 Joules.

## FAQs
