The speed is zero at the points where there is a change in direction; thus, at points where the object comes to a temporary stop and reverses direction.
Acceleration is an increase in speed during a given interval of time. It measures how quickly an object's velocity is changing. Acceleration can be positive (speeding up), negative (slowing down), or zero (constant speed).
If the average velocity of a duck is zero in a given time interval, then you can say that the displacement of the duck for that interval is also zero. This means that the duck has not moved from its starting position during that time period.
no it cannot be zero as the formula for average speed is total distance/total time . if we will come back to the starting point also then also there is distance covered . so it cannot be zero.
(change in distance) divided by (time interval) = the object's average speed during that time interval.
Acceleration is the rate of change of speed with respect to time during a given interval.

False. Instantaneous speed is distance travelled divided by time, for a very short time interval. (Technically, you take the limit, when the time interval approaches zero.)

Definitely.A car that does zero to 60 in 6 seconds will jam you back into the seat a lot harderthan a car that does zero to 60 in a half hour.Average acceleration is (change in speed) divided by (time to make the change).You can see that the change in speed and the time interval of the change are equally important.
You can calculate a speed by dividing a distance by the time it takes to cover that distance. If you want the instantaneous speed (for situations of variable speed), you need to calculate the distance and time for a fairly short time interval (ideally, the limit, when the time approaches zero).
(change in distance) divided by (time interval) = the object's average speed during that time interval.

The average speed of an object in an interval of time is the distance traveled by the object divided by the duration of the interval.
Speed measured in an infinitely small time interval is known as instantaneous speed. This is the speed at a specific moment in time, as opposed to average speed which considers the total distance traveled over a given time period.
