What is kinetic energy?

Kinetic energy is the energy an object possesses due to its motion. It is defined as the work needed to accelerate an object of a given mass from rest to its current velocity. The formula for calculating kinetic energy is KE = 1/2 * m * v^2, where KE is the kinetic energy, m is the mass of the object, and v is its velocity.

Kinetic energy is the energy of an object in motion. It is defined as the work needed to accelerate a body of mass (m) from rest to velocity (v). The formula for kinetic energy is:

```
Ek = 1/2 mv²
```

Where:

- Ek is kinetic energy
- m is mass
- v is velocity

Kinetic energy is a scalar quantity, which means it has only magnitude and no direction. It is also an additive quantity, meaning the kinetic energy of a system of particles is equal to the sum of the kinetic energies of each particle.

Kinetic energy is a conserved quantity, which means it cannot be created or destroyed. It can only be transferred from one object to another. For example, when two objects collide, the kinetic energy of the objects is transferred to the objects that are hit by the collision.

Kinetic energy is often used to describe the motion of objects in everyday life. For example, the kinetic energy of a car is used to describe how fast the car is moving. The kinetic energy of a baseball is used to describe how hard the ball is hit.
