E-2 Flashcard

Front

What is energy transfer?

Back

Energy transfer involves energy moving from one object to another.

Front

What is energy conversion?

Back

Energy conversion happens when the type of energy changes within an object.

Front

Can energy transfers and energy conversions happen simultaneously?

Back

Yes, energy transfers can happen at the same time as energy conversions.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, which is related to its speed.

Front

What is chemical potential energy?

Back

Chemical potential energy is the energy stored in the arrangements of atoms within a substance.

Front

How can we infer chemical potential energy?

Back

Inferences about chemical potential energy are based on observations of atomic arrangements, which are not directly observable.

Front

What is the difference between observations and inferences?

Back

Observations are direct statements about what is seen, while inferences are conclusions drawn from observations.

Front

What is a chain energy transfer diagram?

Back

A chain energy transfer diagram illustrates the sequence of energy transfers from one form to another.

Front

When is it appropriate to use a chain energy transfer diagram?

Back

It is appropriate to use a chain energy transfer diagram when multiple energy transfers occur in sequence, such as eating a granola bar and then kicking a soccer ball.

Front

What is the significance of speed in kinetic energy?

Back

The speed of an object directly affects its kinetic energy; as speed increases, kinetic energy increases.
