Kinetic energy is the energy an object possesses due to its motion. It is defined by the following formula:

KE = 1/2 * mv²

Where:

* KE is 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)

Here's what this formula tells us:

* The faster an object moves, the more kinetic energy it has. This is because the velocity (v) is squared in the equation.

* The heavier an object is, the more kinetic energy it has. This is because the mass (m) is directly proportional to the kinetic energy.

Examples of kinetic energy in action:

* A car moving down the road

* A ball rolling down a hill

* A bird flying in the air

* A spinning top
