Energy, work, and power
What students will learn
Track energy stored and transferred through work, dissipation, and power within a stated system.
Before this topic
- Force models and displacement
- Graph areas and slopes
Read and connect
Read: Translational Kinetic Energy →
Compare translational kinetic energy while keeping mass, speed, and reference frame clear.
Read: Work →
Calculate work from force direction and signed force-displacement area.
Read: Potential Energy →
Choose an energy reference and describe spring and gravitational configuration energy.
Read: Conservation of Energy →
Build an energy account that includes external work and thermal energy when needed.
Read: Power →
Interpret power as an energy-transfer rate and distinguish constant-force from constant-power motion.
Supporting reading: Rotational Kinetic Energy →
After learning rotation tools, connect the parts’ kinetic energies to rotational kinetic energy.
Before this connection: Angular speed and linear speed; Rotational inertia.
Supporting reading: Torque and Work →
After learning torque, compare rotational work with the area under a torque-angle graph.
Before this connection: Torque and angular displacement; Rotational kinetic energy.
Check understanding
Use the complete prompt to make student reasoning visible, then consult the separate worked reasoning and criteria. A reading completion tick records reading history.
Read work from a force graph →
Decompose the specified graph into areas and explain the total energy transfer.
Explain an energy ledger →
Account for kinetic, potential, and thermal changes and interpret the sign of external work.
