Understanding Motion: Acceleration, Distance-Time, and Speed-Time Graphs Quiz

If a car accelerates from 0 to 60 km/h in 5 seconds, what is its acceleration?

On a distance-time graph, a horizontal line represents:

• Constant speed

• Increasing speed

• Decreasing speed

• No motion

What is the speed of an object that travels 150 meters in 30 seconds?

• 5 m/s

• 180 m/s

• 15 m/s

• 4.5 m/s

On a speed-time graph, what does a horizontal line above the time axis represent?

• Acceleration

• Deceleration

• Constant speed

• No motion

How is acceleration calculated from a speed-time graph?

• By measuring the slope of the graph

• By finding the area under the graph

• By calculating the difference in speed over time

• Both A and C

If a speed-time graph shows a straight line sloping downwards towards the time axis, what does it indicate?

• Constant acceleration

• Constant speed

• Deceleration

• Instantaneous stop

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

• Distance

• Time

• Speed

• Acceleration

If an object's speed-time graph is a straight line parallel to the time axis at 20 m/s, what is the object's acceleration?

How can you calculate the total distance traveled using a speed-time graph?

• By finding the slope of the graph

• By calculating the area under the graph

• By measuring the height of the graph

• By subtracting the final speed from the initial speed

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

• Slow speed

• High speed

• Constant speed

• No motion
