Front

What is energy transformation?

Back

Energy transformation occurs when one form of energy changes into another.

Front

What is the law of conservation of energy?

Back

The law of conservation of energy states that when one object loses energy, other objects must gain it.

Front

What type of energy does a steam engine transform heat energy into?

Back

A steam engine transforms heat energy into mechanical energy.

Front

What type of energy is produced when burning wood?

Back

Burning wood transforms chemical energy into heat energy.

Front

What does it mean to say that energy is conserved in an energy transformation?

Back

It means that the total amount of energy before the transformation is the same after the transformation.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion.

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state.

Front

Can energy be created or destroyed?

Back

No, energy cannot be created or destroyed; it can only be transformed from one form to another.

Front

What is an example of mechanical energy?

Back

An example of mechanical energy is a moving car.

Front

What is heat energy?

Back

Heat energy is the energy that comes from the temperature of matter.
