what is the difference between constant and average speed?
165329
What is the difference between constant, instantaneous, and average speed? constant speed is where the speed is the same throughout and instantaneous speed is speed given at any moment and average speed is a total distance traveled divided by the amount of time it took to travel it.

In simple terms, the space-mean speed is the distance traveled divided by an average travel time, whereas the time-mean speed is an average of individual vehicle speeds. ... For all other cases when the space-mean speed is greater than zero, the time-mean speed will always be greater than the space-mean speed.

The average speed is the distance (a scalar quantity) per time ratio. ... On the other hand, velocity is a vector quantity; it is direction-aware. Velocity is the rate at which the position changes. The average velocity is the displacement or position change (a vector quantity) per time ratio.

The instantaneous velocity is the specific rate of change of position (or displacement) with respect to time at a single point (x,t) , while average velocity is the average rate of change of position (or displacement) with respect to time over an interval.

Speed is a scalar, and average velocity is a vector. Average velocity indicates direction and can be represented as a negative number when the displacement is in the negative direction. Average speed does not indicate direction and can only be positive or zero.

Average speed is measured in metres per second m s − 1 . Instantaneous speed is the speed of an object at a particular moment in time. ... The instantaneous speed of an object can be calculated if we know the distance travelled in a very short period of time.

Speed, being a scalar quantity, is the rate at which an object covers distance. The average speed is the distance (a scalar quantity) per time ratio. ... Velocity is the rate at which the position changes. The average velocity is the displacement or position change (a vector quantity) per time ratio.

If the acceleration is constant, then acceleration = change in speed/time for that change. So the change in speed is the acceleration times the time. You still need to know the initial speed which you add to the change.

An average velocity really takes the distance covered in a given time and the average velocity will be the distance divided by time. ... A true velocity is an instantaneous quantity. The difference term is dX/dt where dt is an infintiesimaly small slice of time and dX is the change in in position during that time.

Average speed does not have to equal the magnitude of the average velocity. People may think that average speed and average velocity are just different names for the same quantity, but average speed depends on distance and average velocity depends on displacement.

Constant acceleration refers to motion where the speed increases by the same amount each second. The most notable and important example is free fall. When an object is thrown or dropped, it experiences a constant acceleration due to gravity, which has a constant value of approximately 10 meters per second squared.

Speed commonly refers to the constant rate of change over a distance. ... Rate is a description of change over time. It doesn't have to do with distance (as with speed).

The average speed of molecules is the mean of all magnitudes of velocity at which molecules of the given gas are moving. The root-mean-square speed of molecules is the speed at which all the molecules have the same total kinetic energy as in case of their actual speed.

Average acceleration is the change of velocity over a period of time. Instantaneous acceleration is the change of velocity over an instance of time. Constant or uniform acceleration is when the velocity changes the same amount in every equal time period.

Summary: “Constant speed” means an object is moving at the same speed throughout. ... Instantaneous speed is a certain speed at a specific instant in time. At a certain instant, what the speedometer reads is the instantaneous speed.

Average speed uses the equation "speed equals distance traveled (d) divided by travel time (t)," or average speed = d ÷ t. Average velocity equals speed in a direction. Average acceleration (a) equals change in velocity (Δv) divided by the time interval of the velocity change (Δt), or a = Δv ÷ Δt.

Speed, velocity and acceleration. Average speed is distance divided by time. Velocity is speed in a given direction. Acceleration is change in velocity divided by time.
