Question

you saw the evidence for newtons second law. when you pulled an object with a small force, the object had a small acceleration. the speed of the object increased, but not very quickly. when you pulled the object with a large force the object had a large acceleration. newtons second law states this: the acceleration of an object is directly proportional to the unbalanced force acting on it. this is a mathematical way of saying that a larger force produces a larger acceleration. as the force gets larger, the acceleration gets larger—a direct proportion. you also found that the same force on a small mass produced a larger acceleration than it did on a large mass. newtons second law states this, the acceleration of an object is... inversely proportional to the objects mass. this is a mathematical way of saying that the larger the mass, the smaller the acceleration. as the mass gets larger, the acceleration gets smaller—an inverse proportion. to achieve a big acceleration, you need to apply a large force to a small mass. in one of the most important science books of all time, the principia, isaac newton wrote his second law of motion. it is interesting both historically and in terms of understanding physics to read newtons second law in his own words: the change in motion is proportional to the motive force exerted, and is made in the direction of the straight line in which that force is exerted. use the highlighter tool to highlight the main points in the passage above. next, outline the main points that you highlighted in the passage.

Explanation:

The passage explains Newton's second law of motion. It states acceleration is directly proportional to unbalanced force and inversely proportional to mass. The original statement from Principia is also provided. Main points are the proportional relationships and the original law statement.

Answer:

1. Newton's second - law: acceleration is directly proportional to unbalanced force.
2. Newton's second - law: acceleration is inversely proportional to mass.
3. Original statement of Newton's second law from Principia: "The change in motion is proportional to the motive force exerted, and is made in the direction of the straight line in which that force is exerted."
