Impulse Multiple choice question

In summary, the impulse imparted to the smaller mass by the larger mass is equal to the impulse imparted to the larger mass by the smaller one. This is because the force and time are the same for both masses, leading to equal impulses on each object.

Homework Statement


In a collision between two unequal masses, how does the impulse imparted to the smaller mass by the larger mass compare with the impulse imparted to the larger mass by the smaller one?

A) It is smaller.
B) The answer depends on how fast they are moving.
C) They are equal.
D) It is larger.

The Attempt at a Solution


B isn't right.

Impulse is the force multiplied by the time for which that force acts.
In this case, what can you say about the force of object 1 on 2 and object 2 on 1?
What can you say about the time for which these 2 forces act?

In conclusion, what can you say about the 2 impulses?
 
  • #3
The force is the same and the time in the same; therefore, the impulse on each object is the same.

Perfect :)

It doesn't depend on how fast they are moving.

The correct answer is C) They are equal. This is because according to Newton's third law of motion, for every action there is an equal and opposite reaction. In a collision between two unequal masses, the impulse imparted to the smaller mass by the larger mass will be equal and opposite to the impulse imparted to the larger mass by the smaller one. This is because the forces acting on each mass are equal and opposite, resulting in equal and opposite impulses.
 

Related to Impulse Multiple choice question

1. What is impulse in the context of multiple choice questions?

Impulse, in the context of multiple choice questions, refers to the force or influence that prompts you to choose a particular answer without fully thinking it through. It can be influenced by factors such as familiarity, gut feeling, or external cues.

2. How does impulse affect our decision-making when taking multiple choice tests?

Impulse can significantly impact our decision-making when taking multiple choice tests. It can cause us to choose the first answer that seems right, even if it's not the best choice. It can also lead to second-guessing and changing our answers, which can negatively affect our overall score.

3. What strategies can we use to combat impulse when taking multiple choice tests?

One effective strategy is to read all the options carefully and eliminate the ones that are obviously incorrect. This can help reduce the influence of impulse and increase the chances of selecting the correct answer. It's also helpful to take breaks and avoid rushing through the test.

4. Can impulse be beneficial when taking multiple choice tests?

While impulse can be detrimental to our decision-making, it can also be beneficial in some cases. If we have studied and prepared well for the test, our initial gut feeling may be the correct answer. However, it's important to still carefully consider all options before making a final decision.

5. Are there any other factors besides impulse that can affect our performance on multiple choice tests?

Yes, there are several other factors that can impact our performance on multiple choice tests. These include test anxiety, time management, and the wording and structure of the questions. It's important to be aware of these factors and develop strategies to manage them effectively for optimal performance.
