Understanding Average Acceleration

What is the primary focus of average acceleration?

• The rate of change of velocity over time

• The rate of change of position over time

• The rate of change of acceleration over time

• The rate of change of speed over time

In the first example, what is the initial velocity of the ball?

• 2.5 meters per second

• 0 meters per second

• 5 meters per second

• 10 meters per second

How is the average acceleration calculated in the second example?

• By multiplying the initial velocity by the time

• By subtracting the time from the velocity

• By dividing the change in velocity by the change in time

• By adding the initial and final velocities

What does the slope of the line on a velocity-time graph represent?

• Average distance

• Average speed

• Average acceleration

• Average velocity

In the graphical example, what is the average acceleration if the velocity changes from 3 m/s to 6 m/s over 5 seconds?

• 0.3 meters per second squared

• 0.6 meters per second squared

• 1.2 meters per second squared

• 1.5 meters per second squared
