Question

momentum and impulse connection
force
greater\thard
harder\tlonger
momentum\tstop
time

momentum is a commonly used term in sports. when sports announcers say that a team has the momentum they mean that the team is really on the move and is going to be ______ to stop. the term momentum is a physics concept. any object with a large momentum is going to be hard to ______.

to stop such an object, it is necessary to apply a ______ against its motion for a given period of ____. the more momentum an object has, the ____ it is to stop. thus it would require a ____ amount of a force or a ____ amount of time or both to bring such an object to a halt. as the force acts upon the object for a given amount of time, the object’s velocity is changed; and hence, the object’s ______ is changed.

Explanation:

Step1: Analyze the first blank

The context is about a team with momentum being hard to stop. From the word bank, "harder" fits as a team with momentum is harder to stop. So first blank: harder.

Step2: Analyze the second blank

The sentence says an object with large momentum is hard to... The word "stop" makes sense here. So second blank: stop.

Step3: Analyze the third blank

To stop an object, we apply a "force" against its motion. So third blank: force.

Step4: Analyze the fourth blank

The period of "time" for which the force is applied. So fourth blank: time.

Step5: Analyze the fifth blank

The more momentum, the "harder" it is to stop (consistent with the first blank's logic). So fifth blank: harder.

Step6: Analyze the sixth blank

To stop a more momentum - carrying object, we need a "greater" force (or more time). So sixth blank: greater.

Step7: Analyze the seventh blank

Or a "longer" amount of time. So seventh blank: longer.

Step8: Analyze the eighth blank

When force acts over time, the object's "momentum" (since momentum is related to velocity change) is changed. So eighth blank: momentum.

Answer:

1. harder
2. stop
3. force
4. time
5. harder
6. greater
7. longer
8. momentum
