Energy Concepts and Transformations

These flashcards cover key terms and concepts related to energy transformations, measurements, and principles essential for understanding energy in physical systems.

Energy

The ability to do work or cause a change in a system.

Joule (J)

The unit of energy measurement, where 1000 J = 1 kJ.

Kinetic Energy

The energy an object has due to its motion, dependent on its mass and velocity.

Potential Energy

Stored energy, such as gravitational potential energy, related to an object's position.

Law of Conservation of Energy

Energy cannot be created or destroyed; it can only be transformed or transferred.

Efficiency

The percentage of useful energy transformed compared to total energy used.

Energy Transformation

The process of converting energy from one form to another.

Gravitational Potential Energy

The energy an object possesses due to its height above the ground, dependent on mass, gravity, and height.

Work

The energy transferred when a force moves an object over a distance.

Power

The rate at which work is done or energy is transferred, measured in watts (W).
