Key Concepts of Physics

1.1 Can you recall and use the SI unit for physical quantities?

metre - m

kilogram - kg

second - s

ampere - A

kelvin - K

mole - mol

Frequency - hertz - Hz

Force - newton - N

Energy - joule - J

Power - watt - W

Pressure - pascal - Pa

Electric charge - coulomb - C

Electric potential difference - volt - V

Electric resistance - ohm - Ω

Magnetic flux density - tesla - T

1.2 Can you recall and use multiples and sub-multiples of units?

Giga - G - ×1,000,000,000

Mega - M - ×1,000,000

Kilo - k - ×1000

Centi - c - ÷100

Milli - m - ÷1000

Micro - μ - ÷1,000,000

Nano - n - ÷1,000,000,000

1.3 Are you able to convert between different units, including hours to seconds?

Hour → second = ×3600

Second → hour = ÷3600

Km/h → m/s = ÷3.6

1.4 Can you use significant figures and standard form where appropriate?

Numbers in standard form are written in the format, a×10^n, where a is a number 1 ≤ a < 10 and n is an integer
