    Study Notes

    Types of Motion

    • Motions can be along a straight line, circular, or periodic
    • Examples of different types of motion:
      • Soldiers in a march past (marching in a straight line)
      • Bullock cart moving on a straight road (motion along a straight line)
      • Hands of an athlete in a race (circular motion)
      • Pedal of a bicycle in motion (circular motion)
      • Motion of the earth around the sun (periodic motion)
      • Motion of a swing (periodic motion)
      • Motion of a pendulum (periodic motion)

    Speed and Motion

    • Objects can move at different speeds
    • The same object can move at different speeds at different times
    • To determine if an object is moving slow or fast, observe the distance it covers in a given interval of time
    • Examples of objects moving along a straight path:
      • Group the motion of these objects as slow and fast
      • Decide which object is moving slow and which one is moving fast based on the distance covered

    Observing Motion

    • Observe the position of objects moving in the same direction at different times to determine their speed
    • The distance moved by objects in a given interval of time can help decide which one is faster or slower
    • Example: Observing the motion of vehicles moving on a road in the same direction
      • Identify the vehicle moving the fastest and the slowest of all
      • Determine the distance covered by each vehicle to decide which one is faster or slower
