Sci

• Physics


  Study of everyday phenomenon and matter and energy and their relationship
• Scalar quantity


  Quantity described by a magnitude
• Vector quantity


  Quantity completely described by both magnitude and direction (Always has a starting point and an endpoint)
• Mechanics


  Subbranch of classical physics that is concerned with the forces acting on bodies
• Statics


  • Focuses on the way in which forces combine with each other to produce equilibrium
• Kinematics


  • Focuses on the motion of the body without regard to the cause of that motion
• Dynamics


  • Focuses on the way in which force produces motion
• Motion


  Movement of an object
• Rectilinear motion


  • Object traveling in a straight path
• Curvilinear motion


  • Object traveling in a curved path
• Angular motion


  • Object travelling at certain angels
• Kinematics


  Deals with the description of motion (concepts of motion: Distance, displacement, speed, velocity and acceleration)
• Distance


  The length of the path taken by an object
• Displacement


  Distance between where the object started and where it ended
• Speed


  The rate at which distance is covered in a given time
• Instantaneous speed


  Speed at any instant
• Acceleration


  The rate of change in velocity at a given time
