Why would it be important to use velocity instead of speed when you describe how a storm is moving?

Velocity as opposed to speed is a vector and is therefore much more useful. For example when driving in a car your speedometer tells you your speed in Mph or KMph. This however does not give you information on where you are going, it only tells you how fast. You could be going north, south, east or west. Velocity on the other hand is a vector, which means it gives you direction and magnitude. So you know the car's speed and direction. Therefore velocity is more important in describing how a storm is moving because it tells you where the storm is going and how fast it is going.

Velocity tells you the direction too.

Describe two forces that can affect an objects velocity?
Friction and Gravity are the two forces that affects an object's velocity. Friction is caused by both air and the surface on which an object is moving. Gravity is caused by Earth.
What is the speed of an object moving on a particular direction?
The speed of an object moving in a particular direction is called the velocity and it's a vector, that is, it has magnitude and direction. Speed is the scalar part of velocity.
How does air cause a pressure against a car windscreen?
When a car is moving, this creates a difference in the relative velocity of the car as compared to the surrounding air. This creates a wind that presses on the windscreen. It doesn't actually matter, in terms of the amount of pressure, whether the car is not moving and the air is moving, or the car is moving and the air is not moving, what matters is only the difference in velocity between the car and the air.
What are two ways a car can be at equilibrium?
Either it is at Rest or Moving with Constant Velocity/Speed.
What does slow mean?
Moving or proceeding with little or less than usual speed or velocity

What would describe both speed and direction of a moving object?
The speed and direction of an object is its velocity.
Describe a situation in which the car has zero speed but has a definite acceleration?
An object moving at constant speed in a circle. Acceleration is rate of change of velocity, as velocity is speed in a certain direction, when moving in a circle an object's velocity is constantly changing, as its velocity is changing it is accelerating.
Moving at constant velocity is also moving with constant speed?
Velocity is Speed in a given direction. Moving at constant velocity is equivalent to say moving with a constant speed in a specified direction. So, moving at constant velocity implicitly means moving with constant speed.
What velocity means?
If you have no velocity, then you aren't moving.
Why do you need to calculate velocity instead of speed?
Speed and Velocity are two different things . Velocity- "the rate at which an object changes its position." Speed- "How fast an object is moving". To calculate speed and velocity, you first need to calculate distance and time. Velocity is considered to be a more logical term
What are diifferent word for object?
a "body" "moving body" an "object" is moving with constant velocity. [OR] a "body" is moving with constant velocity.
What does velocity tell you about a moving object?
Velocity tells you what speed a moving object travels at and in what direction.
How will you describe momentum?
Momentum is the speed or velocity of a moving object. It can be measured by either force of impact or air/water displaced during movement.
Describe two forces that can affect an objects velocity?
Friction and Gravity are the two forces that affects an object's velocity. Friction is caused by both air and the surface on which an object is moving. Gravity is caused by Earth.
What happens to the velocity of a moving body if you change the speed at which the body is moving?
The velocity changes. called acceleration.
What is the differnce between velocity and speed?
Velocity is a vector quantity. So direction is important But speed is a scalar. Body moving around a circle may go with uniform speed but not with uniform velocity as direction is changing continuously
