    "imagine that we hae measured the inertial masses of a proton and an electron, separately, and that we then let them come together to form a hydrogen atom. Is the inertial mass of the atom equal to the sum of the masses of the electron and proton? No; it is a shade less. Why? Because in the formation of the atom with the binding together of the proton and electron, the equivalent of a tiny amount of mass escapes in the form of radiation." Can someone explain why this is?

    How does one go about constructing an acceleration vs. time graph?

    actually, i get confused about slopes in 4th quadrant

    And you want to graph the acceleration of the ball?

    direction of accelration is different when ball goes up and down

    The direction of acceleration due to gravity is always negative. The force of gravity is always pulling the ball back toward earth.

    if acc. is negative so why didnt you plot it in 4th quadrant

    That is the fourth quadrant. I didn't includ the second and third because that would include a negatve value for time.
