Under what conditions is the magnitude of average velocity of an object equal to its average speed?

The magnitude of average velocity of an object equal to its average speed if that object is moving with CONSTANT velocity.


When is speed equal to the magnitude of velocity?

That is the case when you are talking about instantaneous speed and velocity - or when the velocity is constant. In the case of an average speed and velocity, this relation does not hold.


When is average speed of an object not equal to average velocity?

For example, an object goes in a circle, at a speed of 50 km/hour. The average speed is 50 km/hour; the average velocity is zero.


How is velocity different from average speeed?

Velocity is speed and its direction. Average velocity is average speed and its direction.


Does average velocity and average speed have the same number?

velocity is a vector and speed is scalar. Velocity has magnitude and directions, with magnitude being speed. The magnitude of average velocity and average speed is the same.


Is there a circumstance average speed equal to average velocity?

As long as there is no change in direction then they are effectively the same.


Is average velocity vector or scalar quantity?

no its a vector quantity,not a scalar quantity,bcz still it z a velocity bt NT a speed On a typical journey the average velocity is the straight-line distance between the start and finish, divided by the time taken, and it also has a direction. The average speed is the actual distance run, divided by the speed. The average speed might not be equal to the magnitude of the average velocity. For example on a round trip the average speed might be 40 mph, while the average velocity is zero.


Difference between average speed and average velocity?

Direction. Velocity has speed and direction


When do the velocity and speed of moving body become equal?

The magnitude of the velocity is always equal to the speed. But velocity is a vector quantity (has a magnitude and direction) while speed is just a scalar quantity (only magnitude). So velocity and speed are never equal.


How average speed and average velocity are related to each other?

Average velocity equals the average speed if (and only if) the motion is in the same direction. If not, the average speed, being the average of the absolute value of the velocity, will be larger.


When is the average velocity equal to average of velocity for an object?

Always.


Can a body have velocity and speed equal?

YES!!!!!!!!!!!! A body can have equal velocity and speed at the same time. for suppose a body is travelling at 20m/s in north direction then the speed of the body is also equal to 20m/s. hence speed and velocity are equal in this case.


Why is the absolute value of velocity equal to speed?

Velocity is a vector. The magnitude of the velocity - its absolute value - is its speed.


Does the instantaneous speed ever equal the magnitude of its average velocity?

Yes. For a start, this happens when the object moves at a constant velocity. Also, if moving in a straight line, even if the object changes speed there must needs be a moment when its instantaneous speed is equal to its average speed - since it cannot change speed suddenly, it must do so gradually.


Does average velocity have a direction associated with it?

The term "velocity", as used in physics, DOES have an associated direction. Most derived terms, such as "average velocity", also do.


Whats the difference between average velocity and instantaneous velocity?

the instantaneous velocity or speed is the speed a body travels at a particular and average velocity is the total distance an object


When do speed and velocity become equal?

speed and velocity becomes equal when a body is moving on a straight road without changing its direction.


Why is average speed distance divided by time but average velocity is initial velocity plus final velocity divided by 2?

Because velocity is a measurement of change of speed rather than an average constant speed. To get the average speed (as you rightly said) - you divide the total distance travelled by the time taken. The average velocity is the change in speed over time (either an increase or decrease).


Can a body have nonzero average speed but have zero average velocity give example?

An object moving in a circular path at constant speed will have a non-zero average speed and zero average velocity since velocity is a vector parameter,


Can speed equal velocity?

Speed is the size of velocity. But velocity also has a direction. "30 miles per hour" is speed. "30 miles per hour north" is velocity.


Is speed equal to velocity?

Speed is the size of velocity. But velocity also has a direction. "30 miles per hour" is speed. "30 miles per hour north" is velocity.


How is it possible for a car to have an average velocity of zero and an average speed of 65 mph?

If the car has an average speed of 65 mph, when it returns to its starting point, it will have a displacement of zero and an average velocity of zero, because velocity has both speed and direction.


In what condition average velocity is equal to average speed give an example?

When an object is moving along a straight line at a variable speed, we can express the magnitude of the rate of motion in terms of average velocity.It is the same way as we calculate average speed.


Is velocity equal to speed?

Velocity is a vector, which means it has a direction, but speed isn't. Speed is the absolute value of velocity. Velocity can be negative, meaning that the speed is opposite to the direction that you're calling the positive direction.


What is formula for speed?

Velocity is equal to the change in distance divided by the change in time. Speed is the magnitude of velocity
