Electrical, chemical, kinetic, elastic, thermal, gravitational potential, nuclear and magnetic energy.

Question 2

What are 2 energy transfers?

Answer 2

Electrical (work done by moving charges) and heating

Question 3

What are the other 2 energy transfers?

Answer 3

Radiation by light and sound waves and work done (mechanically moving an object)

Question 4

Question 5

What is the energy transfer diagram of a ball rolling down a slope.

Answer 5

Gravitational potential energy to kinetic energy by doing work.

Question 6

What is the energy transfer diagram of a kettle boiling water?

Answer 6

Chemical potential energy to a thermal energy store by an electrical transfer.

Question 7

What is an energy transfer diagram?

Answer 7

A diagram that represents energy transfers with the energy stores in boxes and the energy transfers as arrows. See page 2-3 of 1st year 9 science book.
