General Physics (Part II) Flashcards
What is the First group in Division of Physical
Quantities?
First Group:
Length, Area, Volume and Speed
What is the Second group in Division of Physical
Quantities?
Second Group:
Force, Acceleration, Velocity
It is a quantity that can be
completely described by a
single value called Magnitude.
Scalar Quantity
It is a quantity that includes information about the size, strength, and direction.
Vector Quantity
Magnitude means?
Force
Since Vectors are quantities with specific magnitudes and direction, the most appropriate representation of the vector is __________?
Arrow
It makes good reference points, such as a tree, a sign, or a building.
Stationary Objects.
Every motion of something, it is relative to something else.
Frame Of Reference
How do we know if an object is at motion?
If it changes position relative to it’s frame of reference.
The length of path that a moving body travels.
Distance
Distance commonly expressed in what?
Meter, Kilometer, Centimeter, and Feet
Is Distance a Vector Quantity or Scalar Quantity?
Scalar Quantity
The shortest distance between the initial position and the final position.
Displacement
Is Displacement a Vector Quantity or Scalar Quantity?
Vector Quantity
Refers to how fast the object is moving.
Speed
Speed that is not constant.
Average Speed
Speed of the vehicle at the instant while reading the speedometer.
Instantaneous Speed
Since speed is _________________________, speed is expressed in terms of the unit of distance and unit of time.
Speed is Distance divided by Time
(Distance / Time = Speed)
Unit for Distance?
Meter
Unit for Time?
Second
Unit of Speed
Meters per second (m/s)
Formula of Average Speed
Average Speed is equal to total distance over total time of travel.
