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

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.

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

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

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

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.

Always

Yea it is.

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

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.

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

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

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.

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

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.

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

Ye.s

The initial speed of a given particle.

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