Which answer best describes displacement?

Question

Responses:

Displacement is a scalar quality showing total length of an area traveled by a particular object.

Displacement is neither a vector nor scalar quantity, which accounts for how far away an object is after a period of time has elapsed from its initial starting point.

Displacement is a scalar quantity which accounts for how far away an object is after a period of time has elapsed from its initial starting point.

Displacement is a vector quality showing total length of an area traveled by a particular object.

Answer 1

The best answer that describes displacement is:

Displacement is a vector quality showing total length of an area traveled by a particular object.

However, it's important to clarify that displacement specifically refers to the shortest straight-line distance from the starting point to the ending point in a specific direction, rather than the total length traveled along a path. Thus, while the response mentions "total length of an area traveled," it should ideally emphasize that displacement considers direction and is not the same as distance traveled.

Answer 2

Kelley is playing pool and hits the cue into the nine ball, which is directly in the center of the pool table. The nine ball travels a total of 7 meters before stopping, 1 meter to the left of the initial starting point of the nine ball. Which sentence reflects the correct statement regarding distance and displacement when considering the motion of the nine ball?(1 point)
Responses

The nine ball traveled a distance of 7 meters and was displaced by 1 meter.
The nine ball traveled a distance of 7 meters and was displaced by 1 meter.

The nine ball traveled a distance of 1 meter and was displaced by 1 meter.
The nine ball traveled a distance of 1 meter and was displaced by 1 meter.

The cue ball traveled a distance of 7 meters and was displaced by 1 meter.
The cue ball traveled a distance of 7 meters and was displaced by 1 meter.

The nine ball traveled a distance of 1 meter and was displaced by 7 meters.

Answer 3

The correct statement regarding the motion of the nine ball is:

The nine ball traveled a distance of 7 meters and was displaced by 1 meter.

In this case, the total distance the nine ball traveled is 7 meters (the total path length), while the displacement is the direct straight-line distance from the starting point to the stopping point, which is 1 meter to the left.

Answer 4

What is velocity?
Responses

Velocity is a scalar quantity that tells the distance an object has traveled over a period of time.

Velocity is a vector quantity that tells the force of an object over a period of time.

Velocity is a scalar quantity that tells the acceleration of an object over a period of time.

Velocity is a vector quantity that tells the distance an object has traveled over a period of time.

Answer 5

The best answer that describes velocity is:

Velocity is a vector quantity that tells the distance an object has traveled over a period of time.

However, it's important to note that while velocity is indeed a vector quantity, it is defined as the rate of change of displacement over time, not distance. Therefore, a more accurate statement would be that velocity is a vector quantity that indicates how fast an object is moving in a specified direction.

Answer 6

magine a time-position graph where the velocity of an object is constant. What will be observed on the graph concerning the slope of the line segment as well as the velocity of the object?
Responses:

The slope of the line is negative, and the object will be stationary.

The slope of the line is equal to zero and the object will be in motion.

The slope of the line is equal to zero and the object will be stationary.

The slope of the line is positive, and the object will be stationary.

Answer 7

In a time-position graph where the velocity of an object is constant, the correct observation is:

The slope of the line is equal to zero and the object will be stationary.

However, if the object is in motion with a constant velocity, the correct interpretation should be that the slope of the line is constant (not zero), and the line would be a straight line (either positive or negative slope, depending on the direction of motion). If the slope is zero, it means the object is stationary.

To clarify:

• A positive slope indicates constant velocity in the positive direction.
• A negative slope indicates constant velocity in the negative direction.
• A slope of zero indicates that the object is stationary.

None of the given options correctly describe a constant velocity scenario without confounding the description of motion and slope, so you might consider that aspect when reviewing the answers.

Select the option that best summarizes the reason for the use of position-time graphs when studying physical science.(1 point)
Responses

Position-time graphs show the relationship between the position of an object (shown on the x-axis) and the time (shown on the y-axis) to show displacement.

Position-time graphs show the relationship between the position of an object (shown on the y-axis) and the time (shown on the x-axis) to show acceleration.

Position-time graphs show the relationship between the position of an object (shown on the y-axis) and the time (shown on the x-axis) to show velocity.

Answer 9

The option that best summarizes the reason for the use of position-time graphs when studying physical science is:

Position-time graphs show the relationship between the position of an object (shown on the y-axis) and the time (shown on the x-axis) to show displacement.

In a position-time graph, the position of an object is plotted on the y-axis and time is plotted on the x-axis. The graph illustrates how the position of an object changes over time, which can be used to determine displacement when comparing the initial and final positions.
