Which statements describe velocity and acceleration? Check all that apply.Velocity equals displacement divided by time.All velocities are “instantaneous” and occur only at a point in time.Velocity and acceleration are calculated using the same variables.Acceleration equals change in velocity divided by change in time.Acceleration is always constant; it cannot vary.Average velocity can be found by using several velocities and their total time.

Velocity is displacement divided by elapsed time, so statement A is correct. Acceleration is the change in velocity divided by the change in time, making D correct. Average velocity can also be calculated from multiple velocities and the time spent at each: use each velocity and its time to find the total displacement, then divide by the total time, so F is correct. Velocities can be average or instantaneous, and acceleration can vary.
