What is velocity how is it different from speed?
In common language, the terms are used interchangeably. But in physics, speed is a scalar; velocity is a vector. That is, a speed is just a number (and a unit) - for example, 50 kilometers/hour. But when it is important to distinguish a direction, you talk about a velocity. For example, "50 kilometer/hour to the north". Velocity is a speed AND a direction. "50 km/hour north" and "50 km/hour east" are the same speed but different velocity.
How is speed of a body related its velocity?
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.
It can be important to know the velocity of an object not just its speed because?
We distinguish between speed and velocity because if you add the speedsof objects, their directions are important. For example, the velocity of an airplane with ...
Can an object have constant velocity and but variable speed?
No, an object cannot have constant velocity and variable speed. Velocity is a vector quantity that includes both speed and direction. If the object's velocity is constant, then its speed must also be constant.
Can particle have zero speed and non zero velocity?
No, a particle cannot have zero speed and non-zero velocity simultaneously. Speed is the magnitude of velocity and if speed is zero, then velocity must also be zero.
Can an object acceleration if its velocity is constant?
No. It is a matter of definition. Acceleration is defined as a change of velocity. Technically, one must distinguish between velocity and speed. Velocity is a vector and includes the information about the magnitude (speed)and direction. One can have a constant speed and an acceleration (as in circular motion) but, by definition, constant velocity means zero acceleration.

What is speed in a given direction is called?
Speed in a given direction is velocity.
Are speed and velocity different?
SPEED has the speed only; while VELOCITY has the direction and the speed.

What is speed in a given direction?
Speed in a given direction is called velocity.
How do you find speed if you know the velocity?
Velocity is speed and direction
What is the difference betweenn speed and velocity?
Velocity is speed with a direction
What is instantaneous velocity or speed?
It is the speed or velocity at a particular instant.
How are speed and velocity diffrent?
Speed is a scalar, velocity is a vector. In other words, when the direction of the speed is relevant, it is called a velocity.
The speed of an object and the direction of its motion?
the object's 'velocity'
