## What are the components of velocity?

Since, velocity is a vector quantity, it has two components to it. The magnitude, which is the speed, and the direction in which the motion is happening.

## How do you calculate component velocity?

Velocity is a vector (it has magnitude and direction), so the overall velocity of an object can be found with vector addition of the x and y components: v2 = vx2 + vy2. The units to express the horizontal and vertical distances are meters (m).

**What is the scalar component of velocity?**

Distance, speed, and time are all scalars. Displacement is not a scalar, as it involves both the distance and the direction moved from a starting point. Velocity also includes a direction component, and is therefore a vector quantity.

**What is vertical component of velocity?**

The vertical velocity component (vy) describes the influence of the velocity in displacing the projectile vertically. Thus, the analysis of projectile motion problems begins by using the trigonometric methods discussed earlier to determine the horizontal and vertical components of the initial velocity.

### What is the horizontal component of velocity?

The horizontal velocity component (vx) describes the influence of the velocity in displacing the projectile horizontally. The vertical velocity component (vy) describes the influence of the velocity in displacing the projectile vertically.

### What is velocity and its types?

A physics term, velocity describes the motion of objects. Velocity measures the movement of objects based on their speed and direction. Speed is a scalar measurement since it only defines the magnitude of how fast an object is moving. Velocity is a vector quantity since it describes both speed and direction.

**Is velocity a vector or a scalar?**

Speed is a scalar quantity – it is the rate of change in the distance travelled by an object, while velocity is a vector quantity – it is the speed of an object in a particular direction.

**What is the vertical component of the initial velocity?**

#### How are the components of a velocity vector related?

When we break any diagonal vector into two perpendicular components, the total vector and its components— —form a right triangle. Because of this, we can apply the same trigonometric rules to a velocity vector magnitude and its components, as seen below. Notice that is treated as the adjacent side, as the opposite, and as the hypotenuse.

#### Can a velocity component be in a negative direction?

Note that the s in these formulas refer to the magnitudes of the total velocity vector, the total speed, and can therefore never be negative. The individual components and can be negative if they point in a negative direction.

**Is the vorticity vector always parallel to the z axis?**

In a two-dimensional flow where the velocity is independent of the z coordinate and has no z component, the vorticity vector is always parallel to the z axis, and therefore can be expressed as a scalar field multiplied by a constant unit vector z→ : ω → = ∇ × v → = ( ∂ ∂ x ∂ ∂ y ∂ ∂ z ) × ( v x , v y , 0 ) = ( ∂ v y ∂ x − ∂ v x ∂ y ) z → .

**How to determine the z component of a vector?**

(BTW, you mean angle FROM the x-y plane, right?). theta is the angle IN the x-y plane. There are lots of vectors in three dimensions that have the same x-y plane angle, but very different z components. What I meant to ask was, Is the only way to determine the z-component for the scenario I described by introducing a second angle, ϕ?
