Question
( True, False) If the displacement of a particle is decreasing at a constant rate its velocity is constant.
( True, False) Knowing the position and velocity of a particle allows its future position to be predicted even if its acceleration is unknown.
( True, False) Average acceleration and instantaneous acceleration are always the same.
( True, False) Instantaneous velocity is the derivative of the displacement time function.
( True, False) The slope of the velocity time graph is the instantaneous acceleration.
