kinetic energy
Definition
Kinetic energy is the energy of motion. Everything that moves has kinetic energy. The faster something moves, the more kinetic energy it has.
Some examples of kinetic energy include:
- A car moving down the road
- A ball rolling across the ground
- A bird flying through the air
- A person running
Kinetic energy can be used to do work. For example, a car can use its kinetic energy to move people and objects. A ball can use its kinetic energy to hit a target. A bird can use its kinetic energy to fly. A person can use their kinetic energy to do work, such as running, jumping, or lifting objects.
How can the word be used?
The kinetic energy of the waves is used to power a turbine.
Different forms of the word
Noun: kinetic energy (plural: kinetic energies).
the energy of motion.
Adjective: kinetic.
relating to kinetic energy.
Verb: to kineticize.
to give kinetic energy to something.
Etymology
The word "kinetic" comes from the Greek word "κίνησις" (kinesis), which means "motion". The word "energy" comes from the Greek word "ἐνέργεια" (energeia), which means "activity" or "work".
So, kinetic energy is literally the energy of motion. It is the energy that is possessed by an object due to its motion. The greater the mass of an object and the faster it is moving, the more kinetic energy it has.
