# Summary of Energy 1

You have finished the 1st half of the Energy discipline! We have been through the unblurred points in the lists below. Continue to to complete the Energy discipline.

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$$W=F\Delta s$$
Work-energy theorem$$W=\Delta K$$
Energy conservation law $$E_1+W+Q=E_2$$
Power$$P=\frac{\mathrm dE}{\mathrm dt}$$
New phenomena
Energy$$E$$
Equilibrium$$\sum \vec F=0$$ $$\sum \vec \tau =0$$
No-energy rolling
