Dynamics (Physics)

Dynamics:

Dynamics is the name given to the rules of motion. It’s something that you would think would be one of the first things to be figured out, but wasn’t fully locked down until fairly recently. That being said the rules haven’t changed much and are fairly predictable, at least on large scales.

Scalar quantities:

·         - Have a magnitude only.

·         - Energy, Length, Mass, Speed, Temperature and Time are all scalar quantities.

Vector quantities:

·        -  Have both a magnitude and a direction

·         - Displacement, Force, Velocity, Acceleration and Momentum are all vector quantities.
