IB Physics SL A.3.6 Mechanical energy
Practise describing how kinetic and potential energies change in mechanical systems and quantifying partial transfer between them.
How this is tested
- calculate speed when only a stated fraction of lost GPE becomes KE, using 1/2 mv^2 = fraction × mgh
- describe energy changes through a motion sequence, for example GPE to KE, then KE to ball motion and heating
