Question

distinguish between terms speed and velocity​

Answer 1

✨SPEED:

◼Speed is a scalar quantity

◼It is the magnitude of the velocity.

◼It is calculated by the displacement of space per a unit of time.

✨VELOCITY:

◼Velocity is a vector quantity

◼When giving the velocity we must specify the magnitude (speed) and the direction.

◼It is calculated by the displacement of space per a unit of time in a certain direction.

Answer 2

Speed -

1. Speed refers to the distance covered by an object in unit time.
2. Scalar quantity.
3. Rapidity of the object.
4. Will not be zero.
5. Change of distance.

Velocity-

1. Velocity refers to the displacement of the object in unit time.
2. Vector quantity.
3. Rapidity and position of the object.
4. Will be zero.
5. Change of displacement.
