Accelerate Your Understanding

The slope of the curve of velocity versus time

The rate at which the velocity of a particle is changing at any instant (correct)

The second derivative of the position of a particle with respect to time

The average acceleration of a particle over a time interval

$a_{avg} = \frac{v_2 - v_1}{t_2 - t_1}$ (correct)

$a_{avg} = \frac{v_1 - v_2}{t_2 - t_1}$

$a_{avg} = \frac{v_1 - v_2}{t_1 - t_2}$

$a_{avg} = \frac{v_2 - v_1}{t_1 - t_2}$

By taking the second derivative of the position with respect to time (correct)

By taking the derivative of the velocity with respect to time

By taking the first derivative of the position with respect to time

By taking the integral of the position with respect to time
