Kinematics Flashcards
What is kinematicics
It describes the appearance of motion; in its form, pattern, or geometry(shape) ox motion with respect to time
The two types of kinematic analysis are
Qualitative and qualitative
Qualitative analysis describes motion
Visually (how it looks)
Qualitative analysis describes motion
With more precise measurements (involves determining numbers)
The two main types of motion are
Linear and angular
Linear motion is
Motion along a line
The two subtypes of linear motion are
Rectilinear and curvilinear
Rectilinear motion
Is motion along a straight line
Curvilinear motion
Is motion in a curve path
Angular motion
Is motion around an axis of rotation
Linear displacement is
The change in position from its intinal position to its final position
Is linear displacement a vector quantity or a scalar quantity
A vector quantity
Is distance a vector quantity or a scalar quantity
A scalar quantity
Displacement is measured in
Meters (m)
Displacement is measured in
Meters (m)
Linear velocity is
The change in portion that occurs in a specific period of time (rate of change in postion)
The formula for linear velocity is
V= triangle p/ triangle t
Speed is the scalar or vector equivalent to velocity
Scalar
The formula for speed is
Speed= distance/ triangle t
The unit used for speed is
Meters per second (m/s)
Linear acceleration is
The change in velocity that occurs in a specific period of time (rate of change in velocity)
When there is no change in velocity; this means acceleration is
Zero
The equation fur linear acceleration is
A=triangle v/ triangle t
The unit of measure for acceleration is
Meters per second squared (m/s^2)
Finding acceleration on a graph you will use
Rise over run
