Consider a particle undergoing positive acceleration. (1) what is the shape of the position-time graph? (2) How do we determine an instantaneous velocity from the position-time graph?

  • Physics -

    if it is positive constant acceleration, distance is increasing with the square of time. Parabola shapped.

    2. Vinst is the slope of the tangent to the position time curve.
