Motion

• Motion is a change in the position of an object over time
• Frame of reference


  A fixed point of position used to observe the motion of an object
• To completely define the motion of an object, one should note the change in its position over time in relation to the frame of reference
• Motionless/at rest/stationary


  An object that does not change its position with respect to the frame of reference
• Motion


  An object that changes its position from one point to another with respect to the frame of reference
• Distance


  How far two objects (or points) are from one another, the total space covered by a moving object
• Displacement


  Distance with direction, the shortest distance covered by an object from the initial to its final position
• Time


  The duration of a period or how long an object is moving
• Speed


  The rate of change in the position of a moving object, how fast an object moves
• Velocity


  Speed with direction, the rate of change in the position of a moving object with respect to a frame of reference
• Acceleration


  The rate of change in velocity over a certain period of time, when there is a change in velocity
• Maps are useful tools in locating yourself and determining distances and displacements when traveling
• Motion


  The change in the position of an object in relation to the frame of reference or fixed point
• Descriptors of motion


  • Distance
  • Displacement
  • Time
  • Speed
  • Velocity
  • Acceleration
• Distance


  The total space covered by a moving object
• Displacement


  Distance with direction. The shortest distance covered by an object from the starting point to its final point
• Time


  How long an object is moving
• Speed


  The rate of change in the position of a moving object
• Velocity


  The speed with direction. The rate of change in the position of a moving object with respect to the frame of reference
• Acceleration


  The rate of change in velocity over a certain period of time
• Motion refers to the change in the position of an object in relation to the frame of reference or fixed point
• The motion of an object can be described using its different descriptors: distance, displacement, time, speed, velocity, acceleration
