Vectors and Scalars
This video aims to explain the differences between vectors and scalars.
Corrections: I said the force of gravity but meant to say acceleration during the vector examples, and I forgot to write down my units when finding the components of the vector.
The components should be
x = 5m/s*cos(45˚)
y = 5m/s*sin(45˚)
because the units of the vector are conserved in its components.
