Summary of the Energy discipline
You have finished the 2nd and final half of the Energy discipline! With disciplines completed up until here, the door is open to several categories such as that about waves and oscillations, thermodynamics, electronics and more.
All learned properties and mechanisms are stored as memories on your profile, where you can always go to brush them up. If you struggle with any topics in the tests, the Energy classroom is a great place to seek aid.
New properties  

Kinetic energy  $K$ 
Gravitational potential energy  $U_g$ 
Elastic potential energy  $U_\text{elastic}$ 
Work  $W$ 
Heat  $Q$ 
Power  $P$ 
New mechanisms  

Kinetic energy  $$K_\text{trans}=\frac 12 mv^2$$ 
$$K_\text{rot}=\frac 12 I\omega^2$$  
Potential energy  $$\vec F=\nabla U$$ 
$$U_g=mgh$$  
$$U_\text{elastic}=\frac12 k\Delta L^2$$  
Work  $$W=F\Delta s$$ 
Workenergy theorem  $$W_\text{all}=\Delta K$$ 
Energy conservation law  $$E_1+W+Q=E_2$$ 
Power  $$P=\frac{\mathrm dE}{\mathrm dt}$$ 
New phenomena  

Energy  $$E$$
