We learned about many things this first quarter in physics.
We studied were scientific notation, the metric system and dimensional
analysis. Scientific notation is an easier way to represent extremely
large or extremely small numbers in terms of decimal numbers between 1
and 10 multiplied by a power of ten. 0.0000000348 can also be written as
3.48 x 10^-8.
We also studied the differences between scalar and vector quantities. Scalar is a quantity that has magnitude while a vector is a value that has both magnitude and
direction (oh yeah!). An example of this would be, if a scalar quantity
is 10 steps, a vector quantity would be 10 steps north. Scalar is
measured in distance (meters) and vector is measured in displacement
(also in meters). Distance in physics can simply be defined as how far.
Displacement is defined as distance with direction.
Opps I forgot to comment this morning! Hey but this is a great job at summarizing what we learned during 1st quarter! Bet we're always gonna remember a vector as having direction, AND magnitude! (Ohh yeah :D)
