Question 6 (3 points)
Student A states that when she sits down on a chair, she is exerting a force on the chair and that is all that happens. Student B states that when she sits on a chair, the chair is actually exerting a force back on her in reaction to her force exerted upon the chair. Which student is correct and why?

Question 6 options:

Student A is correct because Newton's 3rd Law of Motion states that for every action there is an equal and opposite action and the chair does not show any reaction.

Student A is correct because Newton's 1st Law of Motion states that if the chair exerted a force on the student, her motion would change.

Student B is correct because Newton's 1st Law of Motion states that if the chair were to be exerting a force on the student, her motion would change.

Student B is correct because Newton's 3rd Law of Motion states that for every action there is an equal and opposite reaction and the chair's action counteracts the student's so that neither move.

Which statement best explains the difference in the final rate of acceleration of mass as it was pushed?

Question 8 options:

The final acceleration of all objects will be equal since force does not affect how fast an object will speed up.

The final acceleration of all objects will be equal since the mass did not change during each trial.

Question 17 (3 points)
Use the graph below to answer the question that follows.

(graph from BBC Bitesize)

Which of the descriptions match information graphed?

Question 17 options:

The driver traveled at a very high constant speed, maintained that speed for a few seconds before going back to the start just as quickly where she stopped again. She then increased her speed before maintaining a slow constant speed.

The driver accelerated quickly to merge into highway traffic. She was able to maintain her speed for a few seconds before having to brake hard and come to a stop. Traffic started moving again and she was able to maintain a slow constant speed.

The driver had to go quickly up a steep hill, paused at the top and then descended back down the other side of the hill where she paused again before going up a slightly less steep hill and parking.

The driver pulled out of the parking spot, stopped for 2.5 seconds and then reversed back into the space and stopped again. She was able to then move out of the space more slowly, but then had to stop again.

Question 21 (3 points)
Two students are practicing hitting baseballs off of a tee. The first student says the baseball has the same amount of inertia regardless of how hard you hit it, but it will accelerate twice as fast if you hit it with twice the force. The second student argues that it will accelerate twice as fast if you hit it with twice the force, but says the ball that is hit harder will have twice the inertia. Who is correct, and why?

Question 21 options:

The first student is correct, because inertia describes an object's resistance to change in motion with respect to its amount of mass only.

The first student is correct, because inertia describes the energy that an object contains when it is not moving.

The second student is correct, because inertia describes an object's resistance to change in motion with respect to its amount of mass and speed.

The second student is correct, because inertia describes the energy that an object contains, and objects that are moving have more energy.

Answer 1

Here are the answers based on the information you've provided in your quiz:

Question 1:
a straight slanted line with a positive slope

Question 2:
Without the graph to analyze the data, I can't provide the acceleration. The formula for acceleration is (final velocity - initial velocity) / time.

Question 3:
It must have a constant velocity

Question 4:
velocity

Question 5:
Another force occurs that is equal in size and opposite in direction.

Question 6:
Student B is correct because Newton's 3rd Law of Motion states that for every action, there is an equal and opposite reaction, and the chair's action counteracts the student's so that neither move.

Question 7:
a small car

Question 8:
The final acceleration of Trial 2 will be twice the acceleration of Trial 1 and half the acceleration of Trial 3.

Question 9:
Jose (since the speed data is missing, this is assumed based on typical runners, adjust as necessary when viewing the image).

Question 10:
Without the images to analyze, I am unable to provide an answer. Typically, a graph representing an object at rest would be a horizontal line parallel to the x-axis.

Question 11:
Similar to Question 2, without data shown in the graph, I cannot provide an answer.

Question 12:
If graphs are provided, the graph with the steeper slope would represent faster speed.

Question 13:
Without the image and data, I cannot provide an answer. Speed calculations can be done with the formula: speed = distance/time.

Question 14:
Without the images, it cannot be answered precisely. Usually, a linear graph indicates constant speed.

Question 15:
Similar to Questions 2 and 11, further data would be needed for this calculation.

Question 16:
Similar to Questions 2 and 11, further data would be needed for this calculation.

Question 17:
The driver accelerated quickly to merge into highway traffic. She was able to maintain her speed for a few seconds before having to brake hard and come to a stop. Traffic started moving again and she was able to maintain a slow constant speed.

Question 18:
Please provide more context or data relevant to this question.

Question 19:
Segments C-D

Question 20:
Bounce #4 used the greatest amount of force (not necessarily true; this requires more context on force applied).

Question 21:
The first student is correct, because inertia describes an object's resistance to change in motion with respect to its amount of mass only.

Question 22:
Acceleration

Question 23:
friction

Question 24:
Newton's First Law

Question 25:
remain in motion.

Question 26:
Newton's Third Law.

Data Provided:

• Name: Patel, Jacobia, Mary Beth, Jose
• Distance: 20 m, 10 m, 30 m, 10 m
• Time: 2 seconds, 1 second, 2 seconds, 3 seconds

Calculating Speed for Each Runner:

• Patel: 20 m / 2 s = 10 m/s
