 0 answersPost by kathy jarman on November 16, 2012Regarding slide time 17:40ish, wouldn't the average speed be 10/2/5 = 1 m/s since the object is starting from rest? If not, when would you divide by 2 to get the average? 0 answersPost by Jenny Hua on October 5, 2011Thank you.

If yes and do speedometer in car tell us instantaneous velocity or speed.i think that instantaneous speed is equal to instantaneous velocity of an object because both are take in very small interval of time and in this time period direction of object is same because it is just differentiation of a motion of object..! Im So Confused HelP Me :)

Motion in One Dimension

• The position of a particle moving along the x-axis is the x-coordinate of the particle; it may be positive or negative.
• Displacement is the final position minus the initial position; it may be positive or negative.
• Average speed = Distance/Time.
• Average velocity = Displacement/ Time.
• Instantaneous velocity is the rate of change of position.
• Instantaneous acceleration is the arte of change of velocity.
• If acceleration is constant, some simple relations hold among the displacement, velocity, acceleration, and time.
