What is average velocity?
Average velocity is def.ined as the ratio of total displacement to total time taken.
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,
Why average velocity of molecules in gas zero whereas the average square of velocity is not zero?
Because squaring a velocity removes its sign. A velocity may be negative, but it's square is always positive. If two velocities are +5 and -5, their average is zero. But both squares are +25, so the average square is +25.
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.
What does the area under the acceleration-time graph represent?
its the velocity
Which describes average velocity of a uniclycle going around in circles?
Every time the unicycle returns to its starting point, the average velocity equals zero. The total displacement divided by the time.
Which describes the average velocity of a bicycle going at a constant speed in a constant direction?
Every time the unicycle returns to its starting point, the average velocity equals zero. C. The total displacement divided by the time.
When average velocity and average speed is equal?
For the instantaneous value of average velocity, average speed and average velocity are equal.
Can speed and velocity be the same?
No, they are two very different terms.Velocity describes the speed and the direction of an objects movement.Keep in mid that average speed is distance over time.Average speed describes how far an object moves during a certain amount of time.Sometimes people may use the terms fast or slow referring to speed.
How is velocity different from average speeed?
Velocity is speed and its direction. Average velocity is average speed and its direction.
What is the distance an objects moves divided by the time it took to move that distance?
This describes the average speed. If there is a direction specified that the distance has moved, then it will be a vector, and called average velocity.
When is the average velocity equal to average of velocity for an object?
Always.
What is average velocity?
Average velocity is def.ined as the ratio of total displacement to total time taken.
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.
Is the total distance divided by the total time?
Acceleration equals velocity divided by time i.e a=v/t The S.I unit of Acceleration is m/s2
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.
What is the best definition of velocity?
The speed of something in a given direction.
