KE = 1/2 * mv²

Where:

* KE is the kinetic energy (measured in Joules)

* m is the mass of the object (measured in kilograms)

* v is the velocity of the object (measured in meters per second)

Explanation:

* Kinetic energy is the energy an object possesses due to its motion.

* The formula shows that kinetic energy is directly proportional to both the mass and the square of the velocity.

* This means that a heavier object moving at the same speed will have more kinetic energy than a lighter object, and an object moving faster will have more kinetic energy than an object moving slower.

Example:

Let's say we have a car with a mass of 1000 kg moving at a speed of 20 m/s. The kinetic energy of the car can be calculated as follows:

KE = 1/2 * 1000 kg * (20 m/s)²

KE = 1/2 * 1000 kg * 400 m²/s²

KE = 200,000 Joules

Therefore, the kinetic energy of the car is 200,000 Joules.
