YOUR TEACHING MATERIALStart with what
you’re learning.
In a closed system, energy can be transferred or transformed. The total energy stays constant.
Original example note
The plan: bring your notes, readings or slides. Use a course outline to guide coverage.
PRACTISE THE WHYAnother question.
A better explanation.
A ball falls with negligible air resistance. Which energy change explains its increasing speed?
A Gravitational potential → kinetic
B Kinetic → gravitational potential
Reveal the example explanation
As the ball falls, gravitational potential energy decreases and kinetic energy increases. With negligible air resistance, the total mechanical energy stays constant.
