Kinetic Energy

Kinetic energy is the energy that an object possesses due to its motion. When an object is in motion, it has the ability to do work and cause change. The amount of kinetic energy that an object has depends on its mass and its velocity.

Formula for Kinetic Energy

The formula to calculate kinetic energy is:

KE = 0.5 * m * v^2

Where:

• KE = kinetic energy (in joules)
• m = mass of the object (in kilograms)
• v = velocity of the object (in meters per second)

Units of Kinetic Energy

The SI unit of kinetic energy is the joule (J), which is equal to one kilogram meter squared per second squared (kg * m^2/s^2).

Example

For example, if a car with a mass of 1000 kg is traveling at a velocity of 20 m/s, we can calculate its kinetic energy as follows:

KE = 0.5 * 1000 kg * (20 m/s)^2 = 200,000 joules
