## Study Notes

Kinetic energy is defined as the energy possessed by an object due to its motion. It's calculated using the formula ( \frac{mv^2}{2} ), where m represents mass and v stands for velocity. This type of energy has units of joules when it comes to SI units. There are two main types of kinetic energy: translational and rotational. Translational refers to the movement of objects through space while rotational relates to the spinning of objects around their axes of rotation. A third form of this energy can also be described as vibrational, which applies to objects oscillating back and forth. Examples of kinetic energy in our everyday lives vary from cars driving down highways, people walking briskly, projectiles being fired out of guns, and water flowing over dams, among others. When it comes to physics, kinetic energy transfers occur commonly with collisions between moving bodies such as billiard balls. Applications of kinetic energy have been used throughout history in areas like transportation, machinery, communication, power generation, manufacturing processes, sports equipment design, and environmental management.
