Energy Transformations and Conservation Flashcard

Front

What is work in physics?

Back

Work is done when a force causes an object to move in the direction of the force. It is calculated as the product of the force and the distance moved in the direction of the force.

What is potential energy?

Front

How does velocity affect kinetic energy?

Back

Kinetic energy is proportional to the square of the velocity. If the velocity is doubled, the kinetic energy quadruples.

Front

What is the law of conservation of energy?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

What is the formula for gravitational potential energy?

Back

Front

What is the difference between kinetic and potential energy?

Back

Kinetic energy is the energy of motion, while potential energy is stored energy based on an object's position or state.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of kinetic and potential energy in a system. It is the energy associated with the motion and position of an object.

Front

What is an example of energy transformation?

Back

An example of energy transformation is a roller coaster: as it climbs, kinetic energy is converted to potential energy, and as it descends, potential energy is converted back to kinetic energy.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance, related to its temperature. It is often considered a form of energy that can be transferred as heat.
