Which mass do you think will move down? CORRECT ANSWER Mass B Which mass do you think will move up? CORRECT ANSWER Mass A Click Play (). What happens? CORRECT ANSWER Mass B goes down until it hits the surface and while Mass B was going down, Mass A was going up. What is the force that pulls mass B downward? CORRECT ANSWER Force of gravity Predict: How do you think the speed at which the heavier object descends depends on the difference between the two masses? CORRECT ANSWER The greater the difference between the masses of the object, the faster the heavier object would descend. Analyze: How does the difference in masses affect the speed at which mass B descends? CORRECT ANSWER The greater the mass the less time it takes for the object to descend. Think and discuss: What do you notice about the effect of adding more and more mass? (In other words, does each 1-kg addition of mass have the same effect?) CORRECT ANSWER Adding more mass does not have a constant effect on the time. The more the mass increases the smaller the difference between the time gets.
