Physics

Magnitude

numerical value and unit of measurement

Direction

path that something takes, the  that must be taken to reach a specific place, the way in which something is starting to develop or the way you are facing. 

• Such as NSWE, up, down, right, left, etc.

Distance

•  is the length of the actual paths traveled

Displacement

•  is the length and direction of the change in position measured from the starting point.

Velocity

is speed with direction or the rate of change in displacement and it can be either positive or n

Average Velocity

•  is the total displacement over the time interval.

Instantaneous Veloity

Velocity at different time intervals

Constant Velocity

Is velocity with no change in magnitude and direction from its starting point to its destination.

Acceleration 

is the change in rate of velocity over time.

Deceleration

is when the object slows down.
