Kinetic energy is the energy an object possesses due to its motion. It is directly proportional to the mass of the object and to the square of its velocity.
Kinetic energy is calculated by multiplying the mass of an object by its velocity squared, and then dividing by two. The formula is KE = 1/2 * m * v^2, where KE is kinetic energy, m is the mass of the object, and v is the velocity.
The relationship between kinetic energy and velocity is direct and proportional. This means that as the velocity of an object increases, so does its kinetic energy. Similarly, when the velocity decreases, the kinetic energy also decreases.
The SI unit of kinetic energy is joule (J). However, it can also be expressed in other units such as kilogram-meter squared per second squared (kg · m^2/s^2) or Newton-meter (N · m).
Yes, kinetic energy can be converted into other forms of energy, such as potential energy, heat, or light. This is known as the principle of conservation of energy, which states that energy can neither be created nor destroyed, but can only be transformed from one form to another.
