Study Notes
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.
