Formulae

Question 1

Distance formula?

Answer 1

D (distance) = T (time) x S (speed)

Question 2

Acceleration formula?

Answer 2

a = Vf - Vi / T (time)

Question 3

OTHERS acceleration formulae?

Answer 3

D = S = AX

1) AX = Vi T + at2 /2
2) AX = (Vf + Vi) x t /2
3) AX = Vf2 - Vi2 /2a

Question 4

Force formula?

Answer 4

F (force) = m (mass) x a (acceleration)

Question 5

Ohm’s law?

Answer 5

I = A (current)
V = voltage
R = Ohms (resistance)

1) I = V/R
2) R = V/I
3) V = I x R

PD: TRIANGLE [V] partido de [I] por [R]

Question 6

What happen if a circuit is connected in series?

Answer 6

The resistances are added one to each other:

R total = R1 + R2 + R3

THE RESULT MUST BY DIVIDED TO THE GIVEN DATA.

Question 7

What happen if a circuit is connected in parallel?

Answer 7

Fractions:

1/Rt = 1/R1 + 1/R2 + 1/R3

then:
mcm till you reach 1/Rt = 1/X

then: solve the simple equation and you’ll get the Rtotal.

THE RESULT MUST BY DIVIDED TO THE GIVEN DATA.

Question 8

Combined gas law?

Answer 8

P (pressure), V (volume), T (temperature).

Boyle’s law:
PV - constant.

Charlie’s law:
P/T - constant

Gay-Lussac’s law:
V/T - constant

Question 9

Translation of “drag” and “thrust”?

Answer 9

Drag: Resistencia
Thrust: Propulsión

Question 10

How do you calculate the following conversions?:
ºC to ºF
ºF to ºC
ºC to K
K to ºC

Answer 10

ºC to ºF > ºF = ºC x 1.8 + 32

ºF to ºC > ºC = 0,56 (ºF + 32)

ºC to K > K = ºC + 273

K to ºC > ºC = K - 273
