Interpreting Speed-Time Graphs: PRS

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

• velocity

• time

• distance

• acceleration

If a speed-time graph is a straight line with a positive slope, what does it indicate about the object's motion?

• The object is moving with a constant negative acceleration.

• The object is moving with a constant velocity.

• The object is at rest.

• The object is moving with a constant positive acceleration.

How can you determine the speed of an object from a speed-time graph?

• By finding the slope of the graph.

• By analyzing the shape of the graph.

• By measuring the distance traveled.

• By calculating the area under the graph.

What does a horizontal line on a speed-time graph indicate?

• constant speed

• no motion

• deceleration

• acceleration

In the speed-time graph shown, what is the acceleration in the first 10 seconds?

acceleration = change in velocity/change in time

• 20 ms^-2

• 0 ms^-2

• 0.5 ms^-2

• 2 ms^-2

If a speed-time graph is a straight line with a negative slope, what does it indicate about the object's motion?

• The object is moving with a constant positive acceleration.

• The object is moving with a constant velocity.

• The object is at rest.

• The object is moving with a constant negative acceleration.

How can you determine the acceleration of an object from a speed-time graph?

• Divide the change in speed by the change in time.

• Calculate the slope of the speed-time graph.

• Find the area under the speed-time graph.

• Measure the distance traveled by the object.

What does a curved line on a speed-time graph indicate?

• The object is stationary.

• The object is moving at a constant speed.

• The object is moving in a straight line.

• The object's speed is changing.

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

• acceleration

• velocity

• distance traveled

• time taken

How can you determine the distance traveled by an object from a speed-time graph?

• Divide the speed by the time.

• Calculate the area under the graph.

• Count the number of points on the graph.

• Measure the slope of the graph.
