The magnitude of the velocity is always equal to the speed. But velocity is a vector quantity (has a magnitude and direction) while speed is just a scalar quantity (only magnitude). So velocity and speed are never equal.

speed and velocity becomes equal when a body is moving on a straight road without changing its direction.

The speed is the MAGNITUDE of the velocity, i.e., without regard to the direction.

For the instantaneous value of average velocity, average speed and average velocity are equal.

velocity means speed of an object and in a definite direction.That shows velocity changes with speed

No. The linear velocity can never be equal when speed is constant. This is because direction is changing and therefore linear velocity changes.

Velocity is a vector. The magnitude of the velocity - its absolute value - is its speed.

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.

No. If the speed varies, the body accelerates, and velocity cannot be constant.

Speed is the size of velocity. But velocity also has a direction. "30 miles per hour" is speed. "30 miles per hour north" is velocity.

Speed is the size of velocity. But velocity also has a direction. "30 miles per hour" is speed. "30 miles per hour north" is velocity.

The magnitude of average velocity of an object equal to its average speed if that object is moving with CONSTANT velocity.

In common speech, velocity means speed, they are the same thing.

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.

Velocity is equal to the change in distance divided by the change in time. Speed is the magnitude of velocity

A body moving at a uniform speed may have a uniform velocity, or its velocity could be changing. How could that be? Let's look. The difference between speed and velocity is that velocity is speed.

Part of every velocity is a speed. Speed is the size of the velocity.But the velocity also has a direction, which the speed doesn't.'30 mph North' and '30 mph West' are the same speed but different velocity.

No. Speed is the magnitude of the velocity vector. In order for two velocities to be equal, they must have equal magnitudes and equal (parallel) directions.

No. Velocity is speed and direction. If you change either variable, the velocity will no longer be constant.

mass x velocity = momentum. (velocity = speed with a direction)

No. Speed is the magnitude of velocity. If the speed varies, so will the velocity, even if you are moving in a uniform direction.

This is because speed is defined as the absolute value of velocity - irrespective of the direction of motion.

Speed is equal to the magnitude of velocity almost always. Speed is total distance / total time no matter which way the distance goes. Velocity is the distance from a starting point divided by total time.

A body is said to move with uniform velocity if it has no acceleration. This implies that the body moves with a constant speed along a straight line path. This also means that the body moves with equal displacements in equal intervals of time, however small these time intervals may be.

-- The magnitude of acceleration is equal to the time rate of change of speed. -- The magnitude of acceleration is equal to the time rate of change of the magnitude of velocity. -- Acceleration and velocity are both vectors.
