Distance & speed vs. Time Graphs

What is the significance of the x-axis on a distance vs. time graph?

• It represents the distance traveled.

• It represents the speed of the object.

• It represents the time elapsed.

• It represents the acceleration of the object.

What is speed?

• Speed is the distance traveled per unit of time, typically measured in meters per second (m/s).

• Speed is the rate at which an object accelerates over time.

• Speed is the total distance covered regardless of time taken.

• Speed is the measure of how quickly an object changes its position.

How can you determine the winner of a race using a distance vs. time graph?

• The runner who reaches the greatest distance in the shortest time is the winner.

• The runner with the longest time is the winner.

• The runner who has the most consistent speed is the winner.

• The runner who starts first is the winner.

What does a downward slope on a speed vs. time graph indicate?

• The object is accelerating.

• The object is moving at a constant speed.

• The object is decelerating.

• The object is at rest.

What does a flat line on a distance vs. time graph represent?

• The object is accelerating over time.

• The object is moving at a constant speed.

• The object is not moving; its distance remains constant over time.

• The object is changing direction.

How do you calculate acceleration?

• Acceleration = (Final Velocity + Initial Velocity) / Time.

• Acceleration = (Final Velocity - Initial Velocity) * Time.

• Acceleration = (Final Velocity - Initial Velocity) / Time.

• Acceleration = Final Velocity / Time.

What is the formula for calculating distance?

• Distance = Speed + Time

• Distance = Speed x Time

• Distance = Speed / Time

• Distance = Time - Speed

What is the difference between speed and velocity?

• Speed is a vector quantity (magnitude and direction), while velocity is a scalar quantity (magnitude only).

• Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

• Speed and velocity are the same; both are scalar quantities.

• Speed is the rate of change of position, while velocity is the total distance traveled.

What is acceleration?

• Acceleration is the rate of change of velocity per unit of time, measured in meters per second squared (m/s²).

• Acceleration is the speed of an object in a straight line.

• Acceleration is the total distance traveled divided by the time taken.

• Acceleration is the force applied to an object divided by its mass.

What does a curve on a distance vs. time graph indicate?

• The object is moving at a constant speed.

• The object is accelerating or decelerating.

• The object has stopped moving.

• The object is moving in a circular path.
