Motion Graphs

What does the slope of a distance-time graph represent?

• Time elapsed

• Distance traveled

• Acceleration of an object

• Speed or velocity of an object

How can you calculate the speed from a speed-time graph?

• Multiply the acceleration by time

• Subtract the initial speed from the final speed

• Integrate the acceleration function over time to find speed.

• Divide the distance by time

Identify the key point on a distance-time graph where the object is at rest.

• When the slope of the graph is positive

• When the slope of the graph is zero.

• When the graph is a straight line

• When the graph is curving upwards

In a speed-time graph, what does a horizontal line indicate?

• Variable speed

• Constant speed

• Decreasing speed

• Acceleration

Calculate the slope of a motion graph if the distance is increasing at a constant rate.

• Decreasing

• Positive

• Negative

• Zero

What does the area under a speed-time graph represent?

• Acceleration of the object

• Time elapsed

• Distance traveled by an object

• Initial speed of the object

Identify the key point on a speed-time graph where the object is accelerating.

• Flat horizontal line

• Negative and decreasing slope

• Positive and increasing slope

• Random zigzag pattern

Explain how to determine the speed from a distance-time graph.

• Calculate the slope of the distance-time graph.

• Find the y-intercept of the graph

• Measure the area under the graph

• Count the number of lines on the graph

What does a steep slope on a distance-time graph indicate?

• No movement

• High speed or rate of change in distance over time

• Low speed or rate of change in distance over time

• Constant speed

How can you find the acceleration from a speed-time graph?

• Find the area under the speed-time graph.

• Calculate the slope of the speed-time graph.

• Divide the y-intercept by the x-intercept.

• Count the number of peaks on the graph.
