TEKS: P.7A/B/C/E Transformation of Energy Vocab

Front

Work

Back

The transfer of energy that occurs when a force is applied through distance; equal to the product of the system’s displacement and the force applied to the system in the direction of displacement.

Front

Joule

Back

The SI unit of work and energy (J); 1 J of work is done when a force of 1 N acts on an object over a displacement of 1 m.

Front

Energy

Back

The ability of a system to produce a change in itself or in the world around it; represented by the symbol E.

Front

Work-energy theorem

Back

States that when work is done on a system, a change in energy occurs.

Front

Kinetic Energy

Back

The energy of a system that is associated with its motion.

Front

Power

Back

The rate at which energy is transformed.

Front

Watt

Back

Unit of power; 1 J of energy transferred in 1 s.

Front

Translational kinetic energy

Back

The energy of a system due to the system’s change in position.

Front

Rotational kinetic energy

Back

Kinetic energy of a system due to its rotational motion, proportional to the system’s moment of inertia and the square of its angular velocity.

Front

Potential energy

Back

Stored energy due to the interactions between objects in a system.
