The Nature of Energy Flashcardizz

Front

What type of energy is related to chemical bonds?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like atoms and molecules.

Front

Which form of energy involves feeling heat coming from an object?

Back

Radiant energy is the energy of electromagnetic waves, which can be felt as heat.

Front

What is potential energy?

Back

Potential energy is stored energy due to an object's position or state, such as a rock at the top of a hill.

Front

Which formula represents mechanical energy?

Back

ME = PE + KE, where ME is mechanical energy, PE is potential energy, and KE is kinetic energy.

Front

What is the correct equation for the energy transformation in a hair dryer?

Back

Electrical energy = thermal energy + kinetic energy + sound energy.

Front

Define kinetic energy.

Back

Kinetic energy is the energy of an object due to its motion, calculated as KE = 1/2 mv².

Front

What is thermal energy?

Back

Thermal energy is the total energy of all the particles in an object, related to temperature.

Front

Explain 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.

Front

What is radiant energy?

Back

Radiant energy is energy that travels in waves, such as light and heat from the sun.

Front

What is the difference between potential energy and kinetic energy?

Back

Potential energy is stored energy based on position, while kinetic energy is energy of motion.
