How do unbalanced forces effect an objects speed?
Definition of Speed: The distance traveled per unit time.

Explanation:
Unbalanced forces cause changes in an objects speed, because the harder you push the first ball(s), the faster the last ball(s) will move. However, if you push the first ball(s) softer, the slower the last ball(s) will move.
How do unbalanced forces effect an objects velocity?
Definition:
Speed and direction.

Explanation:
Velocity affected by unbalanced forces in Newton's Cradle, because if there is an unbalanced force in a certain direction, the ball(s) will go in that direction. If it was balanced, nothing would move.
Newton's Cradle is a device that demonstrates the conservation of momentum and energy.
How do unbalanced forces effect an objects acceleration?
Definition:
Change in speed or direction of an object.

Explanation:
The acceleration of an object as produced by a net force, is directly proportional to the magnitude of the net force in the same direction as the net force, and inversely proportional in the mass of an object.
Shows a change in speed by the cradle eventually stopping.
Shows a change in direction by the balls going left to right, and up and down.
