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 can describe both the speed and direction of an object's motion?
Velocity can describe both the speed and direction of an object's motion. Speed only describes how fast an object is moving, while velocity includes the direction the object is moving in as well.

1 To describe velocity you need to know?
Velocity is a vector quantity that describes the rate and direction of an object's motion. To fully describe velocity, you need to know both the speed (magnitude) at which the object is moving and the direction in which it is moving. This information helps specify both how fast an object is moving and where it is headed.
What would describe both speed and direction of a moving object?
Velocity describes both speed and direction of a moving object.
Speed and velocity how are they alike?
Speed and velocity both describe how fast an object is moving. The main difference is that velocity includes direction, whereas speed is just a measure of how fast something is moving regardless of direction.
Why do you need to calculate velocity instead of speed?
Velocity includes both speed and direction, whereas speed only gives you the rate at which an object is moving. Calculating velocity allows you to understand how fast an object is moving and in which direction it is moving. It is essential for analyzing motion in physics and engineering applications.
What do you need to know to describe a velocity?
To describe velocity, you need to know both the speed of an object and its direction of travel. Velocity is a vector quantity that includes both magnitude (speed) and direction, so specifying both is essential. It is typically denoted with a velocity vector, which indicates the speed and direction an object is moving.
What 3 terms are used to describe motion?
Speed, velocity, and acceleration are commonly used to describe motion. Speed refers to how fast an object is moving, velocity includes both speed and direction, and acceleration is the rate at which an object's velocity changes over time.
How can you describe momentum?
Momentum is the property of a moving object that is determined by its mass and velocity. It is a vector quantity, meaning it has both magnitude and direction. The greater the mass or velocity of an object, the greater its momentum.
What velocity means?
If you have no velocity, then you aren't moving.
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.
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.
