17
Q

Scalar Unit

A

Has just magnitude

18
Q

Vector Unit

A

Has Magnitude and Direction

19
Q

Scalar Arithmetic

A

Simply add or subtract the values as appropriate, remembering to convert all values to the same units.

20
Q

Vector Arithmetic

A

With vectors, direction matters. You may either add and subtract them if the values are parallel, use Pythagoras if the values are perpendicular or use trigonometry in other instances.

21
Q

Acceleration due to gravity

A

9.81 m s-2
