Answer

The change in time

Answer

The acceleration of the car

Question 2

20

meters at

5

seconds, what is the constant speed of the object?

Accepted Answer

<math>5</math> m/s

Answer

Question 3

Which of the following describes the appearance of a distance versus time graph for an object that is stationary (not moving)?

Accepted Answer

A horizontal line with a slope of

20

Answer

A diagonal line pointing upward at a

20

degree angle

Answer

A vertical line moving upward

Answer

A curved line bending toward the y-axis

Question 4

Two moving objects are plotted on the same distance versus time graph. Object A has a steeper line than Object B. What can you conclude about their motion?

Accepted Answer

Object A is moving faster than Object B.

Answer

Object B has been moving for a longer period of time than Object A.

Answer

Object B is moving faster than Object A.

Answer

Object A has traveled a shorter distance than Object B.

Question 5

If an object is moving at a constant speed, what shape will its motion create on a distance versus time graph?

Accepted Answer

A straight diagonal line

Answer

A vertical line

Answer

A horizontal line

Answer

A curved line bowing upward

Question 6

A student graphs the motion of a toy car moving at a constant speed. The graph shows that at

20

seconds the car has traveled

5

meters, and at

4

seconds it has traveled

8

meters. What would be the car's position at

10

seconds?

Accepted Answer

<math>20</math> meters

Answer

<math>40</math> meters

Answer

<math>12</math> meters

Answer

<math>16</math> meters

Question 7

A student is observing an object moving at a constant speed and notices that on a distance versus time graph, the line passes through the points (

20

) and (

5

). What is the constant speed of the object?

Accepted Answer

<math>3</math> units/s

Answer

<math>48</math> units/s

Answer

<math>0.33</math> units/s

Answer

<math>8</math> units/s

Question 8

If the slope of a line on a distance versus time graph is decreasing over time (the line is curving to become flatter), what does this indicate about the object's speed?

Accepted Answer

The object is slowing down.

Answer

The object is moving at a constant speed.

Answer

The object is speeding up.

Answer

The object has stopped moving entirely.

Question 9

A student measures an object's motion and creates a distance versus time graph with a straight line. If the line rises

20

meters on the vertical axis for every

5

seconds on the horizontal axis, what is the constant speed of the object?

Accepted Answer

<math>5</math> m/s

Answer

<math>45</math> m/s

Answer

<math>18</math> m/s

Answer

<math>0.2</math> m/s

Question 10

An object's motion is plotted on a distance versus time graph, showing a straight line that passes through the origin. If the object travels

20

meters in

5

seconds at a constant speed, what is the value of the slope of this line?

Accepted Answer

Answer

There is no slope
