This is because speed is defined as the absolute value of velocity - irrespective of the direction of motion.
When the length of the time is decreased more and more ,average velocity of the particles equals instantaneous velocity.
Velocity is a vector, which means it has a direction, but speed isn't. Speed is the absolute value of velocity. Velocity can be negative, meaning that the speed is opposite to the direction that you're calling the positive direction.
In physics, total distance/TIME is average speed, so this is false. Velocity should be switched out with TIME.
It's a scrambled equation. What you meant to say is, "The absolute value of velocity equals speed."
No, the absolute value of speed does not equal velocity. Speed is a scalar quantity that represents the rate at which an object is moving, while velocity is a vector quantity that includes both speed and direction. The absolute value of velocity is the speed of the object.
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)

Velocity is a vector and its magnitude depends on the direction. If it is positive in one direction, going in the opposite direction it is negative. But speed is a scalar and does not depend on the direction. It has the same value, whatever the direction. That is how the absolute value of velocity is speed.
Velocity is a vector, which means it has a direction, but speed isn't. Speed is the absolute value of velocity. Velocity can be negative, meaning that the speed is opposite to the direction that you're calling the positive direction.
Speed and velocity always have the same magnitude, becausespeed is the magnitude of velocity.The difference is that velocity has a direction but speed doesn't
False. A body traveling at constant speed does not change its velocity, which includes both speed and direction. Therefore, in order to change direction, the body would need to change its velocity, which also involves changing its speed.
distance over time equals the speed/velocity.
In physics, total distance/TIME is average speed, so this is false. Velocity should be switched out with TIME.
