Summary of the Motion discipline

You have finished the 2st half and have completed the Motion discipline! Continue to the Forces discipline, starting with Forces 1.

All learned properties and mechanisms are stored as memories on your profile, where you can always go to brush them up. Don’t forget the Motion classroom for aid, questions and guidance while doing the finishing tasks.

New properties
Speed$v$
Velocity$\vec v$
Acceleration$\vec a$
Jerk, snap, crackle, pop...
Absition, absity, abseleration...
New mechanisms
Definitions$$\vec v=\vec s'$$
$$\vec a=\vec v'$$
Motion equations$$v=v_0+at$$
$$s=s_0+v_0t+\frac12at^2$$
$$v^2=v_0^2+2a(s-s_0)$$
$$s=s_0+\frac12(v+v_0)t$$
Turning & circular motion$$a_\perp=\frac{v^2}r$$
New phenomena
Gravitational acceleration$g$
Centrifugal effect
