Can the average velocity of a particle be zero but not its average speed?
Yes, since velocity is speed and direction its average can be zero. For example say a plane flies from point A to point B at 300 mph and turns around to go from B to A at 300 mph; its average velocity is 0 since it is in the same spot as it started ( the velocity vectors cancel) but its average speed is 300 mph.
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.
Is it possible for a body to have average speed but zero average velocity give reason and example?
Yes it is possible. If a body goes round a circular path then distance covered by one full rotation will be 2 pi r But the total displacement is 0. Hence the average speed exists but average velocity does not exist.
What does the area under the acceleration-time graph represent?
its the velocity
What is an example of constant speed with changing velocity?
Velocity is a vector, thus it has a direction. Therefore, you can change the velocity by changing direction. A great example of this is a ball on a string spinning at a constant speed, but it is continually changing direction, therefore, even though the speed is constant the velocity changes at every instant.
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
Can you have zero displacement and nonzero velocity?
i will give u an illustration, consider an object projected (thrown)with some initial vertical velocity from the ground such that it traces a open downward parabolicpath, in that path the vertical displacement of the body from the point of projection to the point where it strikes the ground is equal to zero,but it have some velocity.
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.
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
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
Can average speed of a moving object be zerogive an example?
No, it can't. Average VELOCITY can be zero, though.
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
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.
