### Physics

Some points of note when dealing with A-Level physics:

· The units m/s will now be referred to as ms^{-1} these are the same
thing.

· A-Level physics is also often concerned with using SI units.
This simply means using meters for distance instead of miles, or kilograms
instead of stone. The following are the SI for their respective quantities:

Force

Newton

Mass

Kilograms (not grams!)

Length

Meters

Time

Seconds

Charge

Coulombs

Pressure

Pascal’s

Energy

Joules

Power

Watts

Current

Amps

· Questions in the exam will often ask for a definition. This
can often be given simply as an equation, for example a definition for
speed can be given as ‘distance travelled divided by time taken’.

· The symbol
may be used, this means ‘change’ e.g. time
means ‘change in time’.
