When an object is a projectile what happens to the x component of the velocity throughout its trajectory?
Depending on the shape, speed and change in attitude (especially a tendency to tumble) of the projectile its losses of speed at various instants along its trajectory could be quite considerable owing to friction. Under many conditions air friction is proportional to the fourth power of speed. Thus, the horizontal component of the trajectory could be subject to considerable loss of magnitude. As one would expect the shape of the projectile will affect it's path considerably too.

How can the horizontal velocity of a projectile be described?
The horizontal velocity of a projectile remains constant if there is no air resistance or external forces acting horizontally. This means that the horizontal component of the projectile's velocity does not change throughout its trajectory, only its vertical component is affected by gravity.
What is the vertical velocity of a projectile at the highest point in its trajectory?
At the highest point in its trajectory, the vertical velocity of a projectile is zero. This is because the projectile has reached its peak height and is momentarily at rest before starting to descend.
How fast is a projectile moving at the top of its trajectory?
At the top of its trajectory, a projectile's vertical velocity is momentarily zero, while its horizontal velocity remains constant. The speed of a projectile at the top of its trajectory can be determined by calculating the magnitude of its velocity vector using the horizontal and vertical components of velocity.
What quantities are zero throughout the flight of a projectile?
The vertical velocity at the highest point of the trajectory, the vertical displacement when the projectile returns to its initial height, and the vertical acceleration at the highest point are all zero throughout the flight of a projectile.
In projectile motion Why is the vertical component of velocity zero at the highest point of the trajectory?
Just before it reaches the highest point, the vertical component of velocity is upward.Just after it passes the highest point, the vertical component of velocity is downward.There's no way you can change from an upward velocity to a downward velocity smoothlywithout velocity being zero at some instant. A.True.

What is the magnitude of the velocity of a vertical projectile at its maximum height is equal to?
The horizontal component of a projectile's velocity doesn't change, until the projectile hits somethingor falls to the ground.The vertical component of a projectile's velocity becomes [9.8 meters per second downward] greatereach second. At the maximum height of its trajectory, the projectile's velocity is zero. That's the pointwhere the velocity transitions from upward to downward.
As a projectile shot at an upward angle rises and falls what happens to its horizontal component of its velocity if you neglect air resistance?
If there wouldn't be air resistance and gravity is the only thing that is effecting the projectile, the projectile will start to fall but it horizontal velocity will remain the same. So it would slow down, it would only change height.
Is the acceleration of a projectile equal to zero when it reaches the top of its trajectory?
No, assuming no air resistance, there will be a constant downward acceleration of 9.8 meters per second square (assuming standard gravity). The vertical component of the velocity will be zero at the top of the trajectory.
How can you throw a projectile so that it has nonzero speed at the top of trajectory?
To achieve nonzero speed at the top of the trajectory, you should throw the projectile upward with an initial velocity greater than zero. This will allow the projectile to continue moving upward even at the top of its trajectory before it begins to fall back down due to gravity.
Describe the trajectory for horizontally fired projectiles along an incline .sketch the trajectory?
When a projectile is fired horizontally along an incline, the horizontal component of its velocity causes it to move along the incline while the vertical component of its velocity causes it to rise and fall. The trajectory will be a curved path that follows the incline uphill before falling back down. The range of the projectile will depend on its initial velocity and the angle of the incline. Unfortunately, I'm unable to provide a sketch here.
What are two velocity components of projectile motion?
The two velocity components of projectile motion are the horizontal component and the vertical component. The horizontal component remains constant throughout the motion, while the vertical component changes due to the acceleration of gravity.
How is the horizontal component of velocity for a projectile affected by the vertical component?
The horizontal component of velocity for a projectile is not affected by the vertical component at all. Horizontal component is measured as xcos(theta) Vertical component is measured as xsin(theta) Whereas theta is the angle, and x is the magnitude, or initial speed.
