... (a) “Upward at constant speed” means constant velocity, which means no acceleration. Thus, the situation is just as it was at rest: T = 65 N. (b) The term “deceleration” is used when the acceleration vector points in the direction opposite to the velocity vector. We’re told the velocity is upward, s ...

... A ball is swung on the end of a string in a horizontal circle. The pulling force of the string on the ball acts as centripetal force and causes the ball to change direction continuously, or accelerate into a circular path. Without the unbalanced force acting on it, the ball would continue in a stra ...
