Question

in the \mass in motion\ lab, a ball was rolled down a ramp to see how far it moved a cup. what did this experiment demonstrate? decreases in velocity decrease an objects mass. increased velocity increases an objects momentum. increases in velocity increase an objects mass. decreased velocity decreases an objects momentum.

Explanation:

Momentum is calculated as mass times velocity ($p = mv$). In the experiment, a ball rolling down a ramp gains velocity. As velocity increases, momentum increases if mass is constant. Also, a decrease in velocity would lead to a decrease in momentum. Mass of an object is not affected by its velocity in non - relativistic cases like this simple experiment.

Answer:

B. Increased velocity increases an object's momentum; D. Decreased velocity decreases an object's momentum
