The hotter an object feels, the faster its particles are moving. Conversely, the colder an object feels, the slower its particles are moving.

Here's why:

* Heat is a form of energy. This energy is stored within the object as the kinetic energy of its particles.

* Kinetic energy is the energy of motion. The faster the particles move, the more kinetic energy they have, and the hotter the object feels.

* Temperature is a measure of the average kinetic energy of the particles. So, a higher temperature means faster particles and a hotter feel.

Think of it like this: Imagine a room full of people. If everyone is sitting still, the room feels calm and cool. But if everyone starts running around, the room feels energetic and hot!
