For the instantaneous value of average velocity, average speed and average velocity are equal.
All of them...?
Only if the two velocities are equal in magnitude but in opposite directions.
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)
yes
For the instantaneous value of average velocity, average speed and average velocity are equal.
An object's average velocity is equal to its instantaneous velocity when the object is moving at a constant speed in a straight line. This means that the object covers equal distances in equal intervals of time, resulting in the average velocity over a period of time being equal to the instantaneous velocity at any given moment within that period.
Always.
1. magnitude of distance covered is equal to the magnitude of displacement. 2. the motion of the object is in a straight line i.e. in a particular direction.
The instantaneous velocity is equal to the average velocity when the object is moving at a constant speed in a straight line.
In uniform motion.
A round-trip to school and back
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.
Average speed is the distance traveled divided by the time taken, and it is a scalar quantity. Average velocity is the displacement divided by the time taken, and it is a vector quantity that includes direction. Average speed and average velocity are only equal when an object moves in a straight line, but when there are changes in direction, they can be different.
No, It is the average velocity.
you are still. motion is at rest.
Yes, yes it is
