Kinetic Energy
Kinetic energy is the energy an object possesses due to its motion. In rigid body mechanics, it combines the effects of translation (moving in a straight line) and rotation (spinning around an axis). For a moving object, its kinetic energy depends on its mass and speed, while for a rotating object, it depends on its mass distribution and rotational speed. The faster an object moves or the more mass it has, the greater its kinetic energy. Essentially, it's the energy of motion, determining how much work the object can do as it moves.

Kinetic energy is the energy that an object possesses due to its motion. Any object that is moving—whether it's a car driving down the road, a baseball flying through the air, or a flowing river—has kinetic energy. The amount of kinetic energy depends on two factors: the mass of the object and its speed. Specifically, if either the mass or speed increases, the kinetic energy increases as well. Kinetic energy is an important concept in physics, helping us understand how energy is transferred and transformed in different systems.
