Q

Frequency

A

Hertz (Hz) = s-1

20
Q

Force

A

Newton (N) = Kg.m.s-2

21
Q

Energy, work, quantity of heat

A

Joule (J) = N.m = Kg.m2.s-2

22
Q

Power

A

Watt (W) = J.s-1 = Kg.m2.s-3

23
Q

Electrical charge

A

Coulomb (C) = A.s

24
Q

Electric potential difference, electromotive force

A

Volt (V) = W.A-1 = Kg.m2.s-3.A-1

25
Q

Capacitance

A

Farad (F) = C.V-1 = A2.s4.Kg-1.m-2

26
Q

Electric resistance

A

Ohm (Ω) = V.A-1 = Kg.m2.A-2.s-3

27
Q

Equation for a straight line

A

y = mx + c

28
Q

Equation for a rectangular hyperbola

A

y = 1/x

29
Q

Equation for a ‘tearaway’ exponential

A

y = e^x

30
Q

Equation for a ‘wash out’ curve

A

y = e^-x

31
Q

Equation for a ‘wash in’ curve

A

y = 1 - e^-x

32
Q

Rules of logarithms

A

logb(M.N) = logb(M) + logb(N)

logb(M/N) = logb(M) - logb(N)

logb(M^K) = K.logb(M)

logb(1) = 0

logb(b) = 1

logb(b^K) = K

b^logb(K) = K

logb(1/K) = -logb(K)

33
Q

What do differentiation and integration determine?

A

Differentiation determines the gradient of a graph at any point, and so the rate of change.

Integration determines the area under a curve.
