The two blocks eventually stop and reverse direction. Â The following graphs best predicts the acceleration of block a as it moves up and down the rough, inclined surface. Graph that looks like as shown below but all on the positive portion.
Acceleration, rate at which velocity changes with time, in terms of both speed and direction. A point or an object moving in a straight line is accelerated if it speeds up or slows down.
Velocity tells the speed and direction of a moving object. Acceleration tells us the rate speed or direction changes.
