Forms of Energy and Energy Transformations

Front

What is radiant energy?

Back

Radiant energy is the energy of electromagnetic waves, which can travel through space. It is the energy associated with light and other forms of electromagnetic radiation.

Front

What is the transformation of energy when a blender is used?

Back

The energy transformation when a blender is used is from electrical energy to mechanical energy.

Front

Define thermal energy.

Back

Thermal energy is the energy that comes from the temperature of matter. It is associated with the motion of particles in a substance.

Front

What form of energy is carried by power lines?

Back

Power lines carry electrical energy.

Front

What is the relationship between electromagnetic waves and radiant energy?

Back

Electromagnetic waves are a form of radiant energy, which is energy transferred through these waves.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion. It depends on the mass and velocity of the object.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. It can be gravitational, elastic, or chemical.

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 mechanical energy?

Back

Mechanical energy is the sum of potential and kinetic energy in an object that is used to do work.

Front

What is chemical energy?

Back

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