Symbols in Physics

Distance is represented by the symbol d.
Displacement is denoted as Δx.
A change in height is indicated by Δh.
The unit of measurement for both distance and displacement is the meter.
The abbreviation for meter is m.

Speed and Velocity

Speed or velocity is symbolized by v.
The units for speed or velocity are measured in meters per second.
The abbreviation for meters per second is m/s.
vi represents initial or starting speed.
vf symbolizes final or ending speed.
Changes in velocity are expressed as Δv.

Acceleration

Acceleration is indicated by the symbol a.
The unit of measurement for acceleration is meters per second squared (m/s²).
The abbreviation for meters per second squared is m/s².

Time

A time interval is represented by Δt.
The unit for measuring time is the second.
The abbreviation for second is s.

Force

Force is represented by the symbol F.
The unit for force is the newton.
The abbreviation for newton is N.
The unit abbreviation N is defined as a combination of simpler units: kg∙m/s².

Mass

Mass is denoted by the symbol m.
The unit of mass is the kilogram.
The abbreviation for kilogram is kg.

Hidden Givens

For an object in free fall, the hidden given is a = g = -9.8 m/s².
If an object starts from rest, the hidden given is vi = 0 m/s.
When an object is dropped, the two hidden givens are vi = 0 m/s and a = g = -9.8 m/s².
When an object comes to a stop, the hidden given is vf = 0 m/s.
