For the instantaneous value of average velocity, average speed and average velocity are equal.
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.
It's not. Unless you add a direction to speed it will not become velocity. Since positive and negative are sometimes used to denote direction, absolute value of velocity may equal speed (certain situations)
Distance = time * average speed (velocity) Average speed = Distance/time
The average velocity in a particular direction = distance travelled in that direction / time taken. Velocity is a vector so the direction is important. If I go from A to B and then return to A my average velocity will be zero. My speed, on the other hand, will not be zero.
yes, the average speed equals distance divided by time
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.
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.
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 there is no acceleration or when there is constant acceleration. When either of these cases is present, the graph of velocity versus time will be linear. When there is linear velocity, the average velocity will equal the instantaneous velocity at any point on the graph.
As long as there is no change in direction then they are effectively the same.
Velocity is speed and its direction. Average velocity is average speed and its direction.
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.
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.
Always.
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.
No. Average velocity is still a velocity.Distance is a product of (a velocity or speed) times (a length of time).
The term "velocity", as used in physics, DOES have an associated direction. Most derived terms, such as "average velocity", also do.
