What causes a change in motion? The application of a force. Any time an object changes motion, a force has been applied. In what ways can this happen? Force can cause an object at rest to start moving. Forces can cause objects to speed up or slow down. Forces can cause a moving object to stop. Forces can also cause a change in direction. In short, forces cause changes in motion. The moving object may change its speed, its direction, or both. We know that changes in motion require a force. We know that the size of the force determines the change in motion. How much an objects motion changes when a force is applied depends on two things. It depends on the strength of the force. It also depends on the objects mass. Think about some simple tasks you may regularly do. You may pick up a baseball. This requires only a very small force. <sep>Does an object's mass has very little to do affect how much its motion changes when a force is applied to it?<sep>No

Ex Output:
No

Thelma James was a prime candidate for a real estate ripoff: She is 68, has precious little money and can't read or write. "I won't lie to you. I was so-o-o excited," the widow and former duplex dweller said of the purchase of her first home, a sagging frame structure on Snowden. "I was glad to get me a house." When James realized she had been swindled she turned to Memphis Area Legal Services, which represented her in a lawsuit. Now, James's monthly house notes have dropped from $796 - more than twice her monthly income - to an affordable $247. Some of the people who took advantage of her through a questionable loan program were sent to jail. "I don't know what I would have done without Legal Services," said James. "They solved a lot of my problems." James is one of more than 3,000 clients served last year by MALS, which provides assistance for civil matters, such as domestic abuse and family-related problems, Social Security and Supplemental Security Income, veterans, housing and consumer fraud cases. Like James, most clients are elderly or female. Some are handicapped. Some need medical care or veteran's benefits. Some are trying to escape eviction or an abusive marriage. And 87 percent live at or below poverty level. Shelby County Mayor A C Wharton recently said Legal Services is important for those who, because of poverty or other struggles in life, think justice is an empty word. "They must be given reason to believe that the law is for them too," said Wharton, a former executive director of MALS. But MALS faces a funding crunch next year, brought on by a $200,000 shortfall from three revenue sources. <sep>How does James fit into the usual clientele of MALS?<sep>She's illiterate

The digestive system is the body system that digests food. It digest food in two ways, mechanically and chemically. Both help in the process of turning food into nutrients. The digestive system also eliminates solid food waste. The major organs of the digestive system include the mouth, esophagus, stomach, and small and large in- testines. These organs all work together to help you gain energy from the food you eat. Digestion starts in the mouth. When food is swallowed, it travels through the esophagus to the stomach. In the stomach, digestion continues and a small amount of absorption of nutrients takes place. Most chemical digestion and nearly all absorption of nutrients take place in the small intestine. This organ consists of three parts: duodenum, jejunum, and ileum. The large intestine is the last stop in the digestive system. This is where water is absorbed. The food not digested is released as waste. <sep>What two things does the digestion system do for the body?<sep>It ingests food, and expels the waste
