Topic 1 - Key Concepts in Physics Flashcards
For Paper 1 and Paper 2
What are S.I units?
+Standard units that scientists use to measure their data
+Eg. mass, length, time, temperature
What are the S.I base units for mass, length, time, temperature?
What are all the S.I base units with a prefix in front?
What are the conversion factors?
What is the conversion factor?
The number of times the smaller unit goes into the larger unit.
How do you get from a bigger unit to a smaller unit?
+To get from a bigger unit [like m] to a smaller unit [like cm], you multiply by the conversion factor
How do you go from a smaller unit to a bigger unit?
+To go from a smaller unit [like g] to a bigger unit [like kg], you divide by the conversion factor.
How do you get from Kg to g and g to Kg?
How do you get from Kj to J and vice versa?
How do you get from m3 to cm3 and vice versa?
How do you get from kg/m3 to g/m3 and vice versa?
