Describing Motion

1-D Kinematics

kinematics
Kinematics
  • Science of describing motion.
    • Words
    • Diagrams
    • Numbers
    • Graphs
    • Equations
    • Develop sophosticated mental models that describe the motion of real-world objects.
coordinate sytems
Coordinate Sytems
  • System used to describe motion that indicates when the zero point of the variable is located and the direction in which the values of the variable increase.
  • Origin: point in which the variable has a value of zero.
  • Position vector: arrow used to identify the position of the moving object at any given time.
  • Length of the position vector is proportional to the distance of the object from the origin and points of origin to the location of the moving object at a particular time.
scalars
Scalars
  • Quantities that are described by magnitude (numerical value) only.
    • Time
    • Mass
    • Temperature
vectors
Vectors
  • Describe magnitude and direction
  • Acceleration
  • Velocity
distance and displacement
Distance and Displacement
  • Distance: scalar quantity. It is referring to how far an object moves “distance covered”.
    • d0 to d1
  • Displacement: vector quantity. Refers to the distance and direction Δd = d1 – d0
velocity vs acceleration
Velocity vs Acceleration
  • Velocity: speed and direction that an object moves.
    • Vector quantity
    • Speed =distance traveled/time of travel s = d/t
    • Velocity = Δposition/time = Δd /Δt
    • Instantaneous speed is speed at any given point of time.
    • Average speed – average of all instantaneous speeds.

Acceleration: rate at which an object changes it’s velocity.

    • Vector quantity
    • Constant Acceleration : when an accelerating object changes Its velocity by the same amount each second.
    • Average acceleration = Δ velocity/time or

a = vf - vi / t
