• Kinematics 


  Branch of Mechanics that describes motion using words, graphs, equations, diagram
• Kinematics does not mind the source of the motion
• Position 


  needed to describe before the motion
• Position

  relevant to a convenient reference frame
• we describe motion with reference to earth
• Motion is relative
• You can only describe motion if there is a reference
• Motion


  change os position of the object over time
• Translational Motion


  movement of object from one position to another along a straight line
• Distance 


  length of path travelled
• Displacement 


  length joining the source of destinations
• delta is change
• Velocity 


  how fast an object is in motion
• Instantaneous Velocity 


  slope of the position vs time graph
• Acceleration 


  rate of change in velocity with time
