Kinetic Energy
Kinetic Energy is the energy that an object possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes.
Definition[edit | edit source]
The kinetic energy (KE) of an object can be calculated from the mass and speed of that object using the equation:
- KE = 1/2 mv^2
where:
- m is the mass of the object,
- v is the speed of the object.
Types of Kinetic Energy[edit | edit source]
There are several types of kinetic energy, including:
- Translational kinetic energy of an object is the kinetic energy due to linear motion.
- Rotational kinetic energy is the kinetic energy due to rotational motion.
- Vibrational kinetic energy is the kinetic energy due to vibrational motion.
Applications[edit | edit source]
Kinetic energy can be harnessed to do work. For example, the kinetic energy of wind can be captured by a wind turbine and used to generate electricity.
