Understanding Motion Graphs

What does a straight line on a displacement versus time graph indicate about an object's motion?

• The object is accelerating.

• The object is slowing down.

• The object is moving at a constant velocity.

• The object is stationary.

How can you determine the velocity from a displacement versus time graph?

• By finding the highest point on the graph.

• By counting the number of peaks in the graph.

• By calculating the slope of the graph.

• By measuring the area under the graph.

What is the main difference between speed and velocity?

• Speed is measured in meters per second squared, while velocity is in meters per second.

• Speed is always positive, while velocity can be negative.

• Speed includes direction, while velocity does not.

• Speed is a vector quantity, while velocity is scalar.

How is average speed calculated?

• By measuring the area under a displacement versus time graph.

• By dividing total distance by total time.

• By dividing total displacement by total time.

• By finding the slope of a velocity versus time graph.

What does a negative slope on a velocity versus time graph indicate?

• The object is moving backward.

• The object is accelerating positively.

• The object is moving forward.

• The object is stationary.

What unit is used to express acceleration?

• Meters per second squared

• Meters per second cubed

• Meters per minute

• Meters per second

How can you calculate displacement from a velocity versus time graph?

• By finding the slope of the graph.

• By measuring the area under the graph.

• By finding the highest point on the graph.

• By counting the number of peaks in the graph.

What does a positive area under a velocity versus time graph represent?

• The object is moving backward.

• The object is stationary.

• The object is moving forward.

• The object is accelerating negatively.

If a velocity versus time graph crosses the x-axis, what does this indicate?

• The object has stopped moving.

• The object has changed direction.

• The object is moving at a constant speed.

• The object is accelerating positively.

What is the significance of the area under the curve in a velocity versus time graph?

• It represents the object's speed.

• It represents the object's acceleration.

• It represents the object's velocity.

• It represents the object's displacement.
