Which of the velocity component of projectile changes and other remain constant why?
the horizontal component remain unchanged because there in no acceleration in horizontal direction
Why does the vertical component of velocity for a projectile change with time where as the horizontal component of velocity doesn't?
Because gravity is acting on the vertical component, exerting a constant -9.8m/s2 worth of acceleration.
Why does the horizontal component of velocity for a projectile remain constant while the vertical component changes?
Since the velocity is constant due to the fact that there are no external forces acting in the horizontal direction, if you neglect air resistance, therefore, the horizontal velocity of a projectile is constant.
Why if the object moves as a projectile the X component of the velocity is constant and the Y component change at the same rate?
The 'x' component of the velocity is usually the label given to the horizontalcomponent. Also, remember, we generally ignore air-resistance in this typeof exercise. When we do that, there is no horizontal force on the object, sothe horizontal component of velocity can't change.The only force on the object is gravity, and that's completely vertical, so onlythe vertical component of velocity can change.
What is velocity of a considered to be constant?
horizontal
Which velocity component changes along the path?
The motion of a projectile is a combination of two motions, a constant speed motion in the horizontal direction, and an accelerated motion in the vertical direction. The velocity component that changes along the path is Vy.
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.
What velocity of a projectile is considered to be constant?
horizontal
How do you find vertical and horizontal components when given the initial velocity?
If the initial velocity is v, at an angle x to the horizontal, then the vertical component is v*sin(x) and the horizontal component is v*cos(x).
Is the velocity of a horizontal moving object constant?
Only if the direction is constant and the speed is constant.
A projectile is thrown with an initial velocity which has a horizontal component of 4 m s What will be its horizontal speed after 3s?
A projectile that is thrown with an initial velocity,that has a horizontal component of 4 m/s, its horizontal speed after 3s will still be 4m/s.
What happens to the horizontal velocity of a ball after it rolls off a table?
The horizontal velocity will be equal to the translational velocity of the ball right before it falls off the table. ============================== When we do exercises that deal with the behavior of the ball after it leaves the edge of the table, we always ignore air resistance. When we do that, the horizontal component of velocity remains constant forever, or at least until the ball hits something.
