Speed and Velocity Quiz

What is the main difference between speed and velocity?

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

• Speed and velocity are the same.

• Speed has both magnitude and direction, while velocity only has magnitude.

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

How is speed defined in terms of distance and time?

• Speed is the time taken divided by distance.

• Speed is the distance covered divided by time.

• Speed is the time taken to cover a distance.

• Speed is the distance covered multiplied by time.

What is instantaneous velocity?

• The change in velocity over time.

• The total distance divided by total time.

• The velocity at a specific moment in time.

• The average velocity over a period of time.

How is average velocity calculated?

• The sum of initial and final velocities.

• The difference between initial and final velocities.

• Total distance divided by total time.

• Total time divided by total distance.

What does a positive velocity indicate on a graph?

• The object is moving at a constant speed.

• The object is moving in the positive direction.

• The object is stationary.

• The object is moving in the negative direction.

How can you tell if an object is moving in the negative direction on a graph?

• The line is horizontal.

• The line is below the x-axis.

• The line is above the x-axis.

• The line is vertical.

What is the significance of a scalar quantity?

• It only has magnitude.

• It only has direction.

• It has both magnitude and direction.

• It has neither magnitude nor direction.

What should you check first when interpreting a graph?

• The color of the lines.

• The legend of the graph.

• The labels on the x and y axes.

• The title of the graph.

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

• The object is accelerating.

• The object is decelerating.

• The object is stationary.

• The object is moving at a constant speed.

What does a sloping line on a distance-time graph represent?

• The object is stationary.

• The object is decelerating.

• The object is moving at a constant speed.

• The object is accelerating.
