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

Yes, you can. Example: An object going around in a circle.


Can object have zero acceleration and nonzero velocity at the same time.give example?

Yes, for example, a car moving at constant speed.


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.


Is it possible that a body has zero speed and nonzero velocity?

No because velocity defined as speed in a given direction so if speed is 0 then velocity must also be 0


When average velocity and average speed is equal?

For the instantaneous value of average velocity, average speed and average velocity are equal.


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.


Can there be zero displacement and nonzero average velocity?

It is not possible because the average velocity is equal to the displacement in a given time interval, ie: V = (displacement) / (time interval) As the zero displacement average speed will also be zero.


Compare and contrast velocity and instantaneous speed?

velocity is just a general term for speed (it could be average velocity or instantaneous velocity). Instantaneous velocity/speed (same thing) is the speed at that second. If you are familiar with calculus, it is the derivative of the position graph. Whereas average velocity is how fast the object is going in, for example, 1 hour, it is the speed that is maintained the whole hour (or the average) Instantaneous would be that at the second, at for example t=1.425, the speed is 24m/h . something along those lines


Difference between average speed and average velocity?

Direction. Velocity has speed and direction


Why can velocity be negative but nonzero speed is always positive?

speed is a scalar quantity with magnitude only but no direction; velocity is a vector with both magnitude (speed) AND direction, which could be positive or negative


Average velocity of a particle is zero but not its average speed .. is it possible?

Yes - for example, if an object moves in a circle.


Can average speed of a moving object be zerogive an example?

No, it can't. Average VELOCITY can be zero, though.


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.


What is the velocity?

Velocity is a speed with a direction (e.g. 20 miles per hour North). your example is an average velocity. velocity is displacement over elapsed time. it is speed. i know this and im only 11


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.


An object has 0 vilocity but it cant have 0 average speed justify?

The correct term is velocity, not velocity.There is no reason why an object cannot have 0 velocity and 0 average speed - relative to some fixed reference point. I assume that your school, for example, has 0 velocity and 0 average speed.


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.


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.


What is the average speed of the car traveling 300km in 6hrs?

Velocity (or speed) = Distance ÷ Time In this example, speed = 300/6 = 50 kph


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.


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


What is an example of the difference between speed and velocity?

Speed is what it is: speed. Velocity is speed in a given direction, a vector quantity.


What is one example of velocity?

One example of Velocity is that if you are running in the same direction, your speed and velocity is the same. But if you are running AROUND the track, your speed is the same but your velocity is changing.


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).
