1

What is Boyle's law?

For a fixed mass of gas, at constant temperature and pressure, the pressure is inversely proportional to the volume. P ∝ 1/V

2

What is Charles' law?

For a fixed mass of gas, at a constant temperature and pressure, the volume is directly proportional to the temperature (in kelvin). V ∝ T (in K) x K - the constant

3

Coulombs law?

Any two point charges exert an electrostatic force on each other - it is directly proportional to the product of their charges and inversely proportional to the square of their separation

4

Faradays law?

The magnitude of the induced EMF is directly proportional to the rate of change of magnetic flux

5

Hookes law?

The force applied is directly proportional to the extension of the spring unless the limit of proportionality is exceeded

6

Archimedes principle?

The upthrust exerted on a body immersed in a fluid (fully or partially), is equal to the weight of the fluid that the body displaces

7

The seven base units?

metre, kilogram, second, ampere, kelvin, mole

8

Factor for P?

x10^15

9

Factor for T?

x10^12

10

Factor for G?

x10^9

11

x10^3

13

Factor for d?

x10^-1

14

Factor for c?

x10^-2

15

21

Pressure regular symbol and then SI?

Pa and Nm^-2

22

Energy or work done symbol and then SI?

J and Nm

23

What equation relates energy and power?

Power = Energy/time

24

Symbol for power and SI unit?

W and Js^-1

25

Frequency SI units?

s^-1

26

Momentum SI units?

kgms^-1

27

How to go from degrees to kelvin?

+273

28

Blue shifted?

If a galaxy is moving towards earth, absorption lines move towards the blue end of the spectrum (as wavelength appears shorter - compressed), red shift is the opposite

29

Hubbles law?

The recessional speed (v) of a galaxy is almost directly proportional to its distance from earth (d) - V = humbles constant x d

30

Newton's law of gravitation?

The force between two point masses is directly proportional to the product of the masses and inversely proportional to the square of their separation
