Rotational kinetic energy is the energy possessed by an object due to its rotation around an axis. It is dependent on the mass and distribution of the object's mass, as well as its angular velocity.
The formula for calculating rotational kinetic energy is E = 1/2 * I * ω^2, where E is the energy in joules, I is the moment of inertia in kilograms per meter squared, and ω is the angular velocity in radians per second.
Linear kinetic energy is the energy possessed by an object due to its linear motion, while rotational kinetic energy is the energy possessed by an object due to its rotation. Linear kinetic energy is calculated using the formula E = 1/2 * m * v^2, where m is the mass of the object and v is its velocity.
Work is the transfer of energy from one form to another, and rotational kinetic energy can be converted into other forms of energy through work. Power is the rate at which work is done, so the greater an object's rotational kinetic energy, the more power it has.
Some examples of rotational kinetic energy in everyday life include spinning tops, wind turbines, and bicycle wheels. In sports, rotational kinetic energy can be seen in the rotation of a discus or a figure skater's spins. In vehicles, rotational kinetic energy is present in the rotating wheels of a car or the propellers of a helicopter.
