Linear Kinematics Terms Flashcards
Acceleration
Change in velocity over time
Apex
Highest point in trajectory of projectile
Average
Occurring over a designated time interval
Curvilinear motion
Movement along a curved path
Differentiation
Process of going from displacement to velocity to acceleration
Distance
Length an object has traveled
General motion
Movement of an object
Initial velocity
Vector quantity incorporating angle and speed of projection
Instantaneous
Occurring during a small interval of time
Integration
Opposite of differentiation
Kinematics
Form, pattern, sequencing of movement with respect to time
Laws of constant acceleration
Formulas relating displacement, velocity, acceleration, and time when acceleration is unchanging
Linear motion
Motion moving in a straight line
Meter
International unit of length
Pace
Inverse of speed
Projectile
- Body is in free fall
- System subject ONLY to forces of gravity/air resistance
- Object propelled through space by force (forces cease after launch)
Projection angle
Angle at which projectile is released from
Projection speed
Magnitude of projection velocity
Range
Horizontal displacement of projectile at landing
Rectilinear motion
Movement along a straight line
Relative project height
Difference between projection height/landing height
Scalar
Expressed by number only
Speed
Change in distance over time
System
Mechanical system chosen for study
