Lenses

Definition: Mirrors on both sides

\n

• Can be concave and convex

  • On both sides
  • On one side

Speed = slop and/or velocity

• If straight line it means that it’s uniform

  \n \n

Total distance = positive + negative

• If positive, north

• If negative, south

  \n \n

Find slope and that will be from d-t to v-t

5 motion equations:

1. D = [(v1+v2)/2] T
2. V2 = V1=AT
3. D = V1T+½ AT2
4. V2T-½ AT2

• D =V1T=½ AT2

1. V22 = V12+2A

2. Va(S) = D/T

   \n

V1 = initial

V2 = final

A = acceleration = slope

D = displacement

• The area between x axis and line/graph

T = time

S = speed

\n

Meter per sec to km per hour = x3.6
