The term for energy of movement

lara31 [8.8K]

Answer;

-Kinetic energy

Explanation;

The energy associated with motion or movement is called kinetic energy.

-Kinetic and potential energies are found in all objects. If an object is moving, it is said to have kinetic energy (KE). Potential energy is stored energy and the energy of position; gravitational energy.

-An object that has motion - whether it is vertical or horizontal motion - has kinetic energy. Kinetic energy is calculated by the formula 1/2mv², where m is the mass of the object and v is the velocity of the object.

-Therefore, kinetic energy depends upon two variables: the mass (m) of the object and the speed (v) of the object.
