Read the paragraph and answer the question:

"Consider a scenario where a rubber ball is placed on a flat table surface. Upon gently pushing the ball, it starts to roll. If the ball is pushed again while it is already moving, its speed increases. Placing your palm in front of the rolling ball will result in a decrease in speed as the ball touches your palm and eventually stops. This demonstrates that force can not only change the ______ of an object but also bring it to a halt. Moreover, when force is applied repeatedly, the ______ of the object also changes, illustrating the effect of continuous force application."
