What is a definition for horizontal velocity as well as vertical velocity?

Horizontal velocity is the speed of something flat ot the ground like a car on the road.\n\nVertical velocity is the up/down speed, like a ball thrown straight up.\n\nIf you throw something on an angle (not straight up) it has some vertical velocity in the up direction and some horizontal velocity along the ground.

here are some simple mechanics formulas dealing with velocity:\n\nv=d/t\na=v/t\nvf^2=vi^2+2ad\nd=vit + 1/2at^2\n\nwhere v is velocity, vi is initial velocity, vf is final velocity, a is acceleration, and t is time.  also the i and the f after the v are just subscripts, and ^2 just means sqared.

velocity is just a term that means "speed" - the distance traveled per time unit \n\nthe "speed of light" is a number - the actual speed (velocity) that light travels, usually reported in meters/second (distance/time)

Constant and uniform are generally used interchangeably.  \n\nConstant velocity means two things: constant speed and constant direction.  \n\nConstant speed means just a nonchanging speed.  You can be going in a circle with a constant speed, but your velocity is not constant because you are constantly changing directions.

x=v(horizontal velocity of water hitting ground)*t( time of travel)\n  = sqrt(2gy) *t; from equation v^2=2gy\nt= sqrt(2h/g); from equation h=.5*g*t^2\nthere you get that equation. I did with kinematics.

linear momentum of a moving body is the "thing" that keeps it moving, given by mass x velocity.\n\nangular momentum is the same "thing" that keeps an object spinning about its axis.

Velocity:\nv=d/t\n\nd=distance\nt=time\n\nAcceleration:\na=(vf^2-vi^2)/2d\n\nvf=final velocity\nvi=initial velocity

I'm not sure what you are asking, but motion is measured with reference to something else.  \n\nFor example, when we say the car is traveling 30 mph down the road, we mean it is traveling that speed in reference to the road.  It would be equally correct to say that car is traveling 60 mph towards you if you were in a car traveling at 30 mph towards it.  In your reference frame, it would be traveling at 60 mph.

Momentum refers to the quantity of the motion that the object have.....It is mainly " MASS IN MOTION "..It depends on mass and velocity....momentum = mass * velocity...or momentum(P) = mass(M) * velocity(V)....Its is a vector quantity...

umm...do you mean slant??\n\nvertical, horizontal, and slant should be it.

The angle is given. Horizontally means with an angle of 0 degrees elevation.\n\nYou can find how long the ball takes to travel 60 ft horizontally (60/147.84 seconds), so, knowing the acceleration due to gravity (which you will have been given), you can calculate how far it must fall in that time.\n\nt = 60/147.84 = 0.405844156\n\ndistance d covered by falling body in t seconds = ½gt²\n\ng = 32.174 ft/sec²\n\nd = 0.5 * 32.174 * 0.405844156 * 0.405844156 = 2.649681386 ft

time usually\n\nThe horizonatal axis is usually the independent (or input) variable and the vertical axis is the dependent (or output) variable whose value depends on the value chosen for the input\n\neg v = f(t)\n\nt is the input and v (= f(t)) is the output\n\nHowever if you had the equation in the form t = g(v) then v would be the input and so the horizontal axis and t would be the output

Velocity is a vector (basically something that has direction and speed) whereas speed it just a magnitude expressed in terms of its absolute value.

You have to keep your two vectors straight....you have one for horizontal motion and one for vertical motion.  To find the velocity on the desk (horizontal), you will need to know the time it took to land.  You can use the formula for gravity: d=1/2gt^2.\nd=1.33\ng=9.8\nt is the variable\n\n1.33=0.5(9.8)t^2\nt=square root of 1.33/4.9\n\nOK.  Now we know the time it took to land.  You can now find its horizontal velocity.  Velocity=Distance divided by time.\n\nVelocity=.25/square root of 1.33/4.9\nVelocity is approximately equal to 0.4799m/s.\nMore exact:0.479857435\nHope that helps.  Let me know if you're still confused.

velocity-height and horizontal movement. 11.2 km/s in order to escape earth's atmosphere (air provides resistance against movement) above 50 km and movement in horizontal direction so that the object falls perpetually towards the earths gravity centre.

Your question is not very clear. Whether your talking about simple harmonic motion or not....x describes position. Velocity describes the rate at which the position is changing. And acceleration describes the rate at which velocity is changing. The short answer is that it's possible to have a negative velocity as well as a negative acceleration.
