What is an increase of speed during a given interval of time?
Acceleration. Deceleration is a decrease of speed during a given interval of time.
How to find acceleration?
Acceleration has two parts ... its size and its direction.To find the size (magnitude):-- pick a time interval-- measure the speed at the beginning of the interval-- measure the speed at the end of the interval-- subtract the speed at the beginning from the speed at the end-- divide that difference by the length of the time interval-- the result is the magnitude of acceleration during that time interval
Can an average speed of moving object be zero?
as the moving object covers some distance in some interval of time and average speed is obtained by dividing the total distance travelled by total time taken
What is the formula to determine the acceleration of an object moving in a strait line?
Acceleration = (speed at the end of some time interval minus speed at the beginning of the interval)/(length of the time interval)
What is Density and Speed?
A material's density is defined as its mass per unit volume. It is, essentially, a measuremement of how tightly matter is crammed together. The principle of density was discovered by the Greek scientist Archimedes.In kinematics, the speed of an object is the magnitude of its velocity (the rate of change of its position); it is thus a scalar quantity. 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; the instantaneous speed is thelimit of the average speed as the duration of the time interval approaches zero .
Instantaneous speed is total distance traveled divided by total time of travel this is true and false?
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.)
Does amount of acceleration depend on both the change in velocity and the time interval of the change?
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.
How do you calculate exact speed?
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).

The amount of distance traveled in a given amount of time measures what?
(change in distance) divided by (time interval) = the object's average speed during that time interval.
What is average speed definition?
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 infinately small time interval?
instantaneous speed
What do you understand by instantaneous velocity?
Instantaneous speed is the velocity of an object at a certain time. For example:- Suppose you are driving in a car and the speedometer constantly varies; this is because the speedometer gives speed at a particular moment of time.
