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.
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.
A bullet fired horizontally over level ground hits the ground in 0.5 seconds If it had been fired with twice the speed in the same direction it would have hit the ground when?
Assuming no affects from air and a smooth geography, both bullets would fall at the same rate of 9.81 m/s^2 toward earth, and hit the ground simultaneously. You have to look at the bullet's velocity as having a horizontal and vertical velocity vectors. The vertical velocity vector is independent from that of the horizontal. The horizontal vector would be the speed at which the bullet is fired, and the vertical vector is the speed at which the bullet falls due to gravity.
When a stone is thrown upward at an angle what happens to the vertical component of its velocity as it rises and as it falls?
The vertical component of its velocity increases at the rate of 9.8 meters (32.2 feet) per second downward every second. Without involving numbers, simply the vertical component will first be upward at what ever velocity it is when split from the horizontal velocity, then (after reaching the peak of its height at which velocity is zero) it will be a downward vector that, yes, will increase with acceleration due to gravity (which is where the 9.8 meters per second squared came from)
How do you draw a horizontal?
It's parabolic. More specifically, it's half a parabola, with a vertex at the point of origin. You see, horizontal and vertical velocity are independent of each other. This means that the projectile will more horizontally at a constant velocity (ignoring wind resistance) equal to its initial velocity. At the same time, the projectile is accelerated downward at a rate of 9.8 m/s2 (approximately). Since it undergoes constant acceleration, it increases in velocity every second exponentially, giving it a parabolic curve. As an interesting side note, since horizontal and vertical velocity are always independent of each other, any velocity (really, any vector) can be represented as its horizontal and vertical components, allowing one to add up the individual components and to find a resultant vector quantity. Here's an example drawing of the curve described: http://www.staff.amu.edu.pl/~romangoc/graphics/M2/1-projectile-motion/M2-3.gif Keep in mind that if the point of origin is at a greater vertical level than the ground, the projectile will fall all the way to the ground, past the horizontal axis.

A ball of mass m rolls off a cliff of height h with a horizontal velocity v it reaches the ground with vertical speed of?
If one assumes air resistance to be negligible, then: final velocity = sqrt( g * 2 * h ) where g is 9.8 metres per second per second. The quantities v and m do not matter, because gravitational acceleration does not depend on mass (all objects fall at the same rate) and because the horizontal velocity is independent of the vertical velocity.
What happens to the gravitational energy of an object as it gets higher in a gravitational field?
-- If the velocity is horizontal, then gravitational potential energy doesn't change. -- If velocity is vertical and upward, gravitational potential energy increases at a rate proportional to the speed. -- If velocity is vertical and downward, gravitational potential energy decreases at a rate proportional to speed.

What is horizontal and vertical amplifier in cathode ray oscilloscope?
The horizontal and vertical amplifier in the cathode-ray oscilloscope are deflection plates. The horizontal amplifier causes the beam to be deflected horizontally at a rate that is uniform. The vertical amplifier causes the beam to deflect vertically.
What does the slope mean on a line graph?
Rate of change of the "vertical" variable in relation to the "horizontal" variable.

What are the two types of motion a projectile has?
If you throw ball at an angle above horizontal, you will see the path of the ball looks like an inverted parabola. This is result of the fact that the ball's initial velocity has a horizontal and vertical component. If we neglect the effect of air resistance, the horizontal component is constant. But the vertical component is always decreasing at the rate of 9.8 m/s each second. To illustrate this, let the initial velocity be 49 m/s and the initial angle be 30˚. Horizontal component = 49 * cos 30, Vertical = 49 * sin 30 = 24.5 m/s As the ball rises from the ground to its maximum height, its vertical velocity decreases from 24.5 m/s to 0 m/s. As the ball falls from its maximum height to the ground, its vertical velocity decreases from 0 m/s to -24.5 m/s. Since the distance it rises is equal to the distance it falls, the time that it is rising is equal to the time it is falling. This means the total time is equal to twice the time it is falling. This is the reason that the shape of the ball's path is an inverted parabola. At the maximum height, the ball is moving horizontally. If you do a web search for projectile motion, you will see graphs illustrating this.
Do all lines have a slope?
Although all lines have the relationship that defines slope, one can argue that not all lines do have one. The exception would be vertical lines. Slope is defined as the vertical rate of change divided by the horizontal rate of change. In the case of a vertical line, there is no horizontal rate of change, and calculating slope would cause division by zero. The closest you could come to expressing the slope of a vertical line would be ∞
Meaning of the slope as a rate of change?
The slope is the ratio of rise over the run. The rise is the change in the vertical distance.The run is the change in the horizontal distance.So the slope is the ratio of two changes, horizontal divided by vertical.
