Why there is no acceleration along x axis during projectile motion?

There is no force that acts upon the object in that direction. Gravity only acts on the y axis. Though there is some wind resistance that does cause a negative acceleration in the x direction. You are probably just being told to ignore this as it is usually negligible.

What's a Projectile motion?
Projectile motion is a form of motion in which an object or particle is thrown near the earth's surface, and it moves along a curved path.
How do you find projectile motion?
Projectile motion is a form of motion in which a projectile is thrown near the earth's surface. When thrown, the projectile moves along a curved path because of gravity. An example of projectile motion is a sprinkler shooting water into the air and the water falling back down to Earth.
Is there any point along the path of projectile where velocity and acceleration vectors are parallel to each other?
no
Is an object sliding along a horizontal table an example of projectile motion?
No. The definition of projectile motion is an object dropped launched into the air, which is acted upon by gravity. (For the basic forms of the motion, air resistance is ignored.)
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.

The height of a projectile in motion is dependent on what?
Projectile motion is a form of motion wherein an object moves along a curved path under the action of gravity only. The height of a projectile in motion is dependent on gravity.

Is the statement 'a body moving with uniform speed along a circular path is subjected to uniform acceleration' true or false justify?
This statement is true. This type of movement is called Uniform Circular Motion. For every circular motion at constant speed, there is a constant radial acceleration (always pointing towards the center of the circle) named centripetal acceleration. This constant acceleration ensures that at every moment during the motion the orientation of the velocity is changed so that the object stays in a circular path.
For motion along a straight line a horizontal line on a speed over time graph indicates graph indicates that what is zero?
For motion at constant speed along a straight line, the acceleration is zero.
Describe the motion of a bus whose acceleration is 0 but whose speed is not 0.?
The bus is in steady motion along a straight line at a constant velocity.
Can a particle moving with uniform speed along a curved path have acceleration?
Yes, due to its change in direction of motion.
How does the direction of the acceleration along determine if the object is speeding up or slowing down?
Take the component of the acceleration along the direction the object is moving. If this component is positive (the acceleration vector, or the relevant component, points in the same direction as the movement), then the object is speeding up.
