Why does a force of gravity has no effect on horizontal component of velocity?
The force of gravity points towards the center of the earth ... the direction we call "down". The force has no horizontal component, so it can't have any effect on horizontal speed.
When constant force is applied to a body then it does it moves with uniform speed?
velocity
If air resistance is neglected what is the motion of an object projected at an angle consists of a uniform downward acceleration combined with what?
a constant horizontal speed
A horizontal force of 100 N pushes a box across a floor at a constant speed. what is the force of friction acting on the box?
If the horizontal velocity is constant, then the horizontal acceleration is zero,and the net horizontal force is zero.But if you are saying that the body was in constant motion and after that the force was applied, then the body will acccelerate because of the force. The net force applied on the body would be equal to the force applied to it when the body was in constant motion as here the force is in direction of the motion and hence the angle will be 0 giving the value of cos 0º as 1. Hence there would be no reduction in the net force
A 125.0 kg box is pushed by a horizontal force F at constant speed up a frictionless ramp which makes an angle of 25.0 deg with the horizontal Find the magnitude of the applied force F?
its really easy

velocity
How must the net force depend on the speed of the moving object in order to obtain uniform circular motion?
The force required to keep a body to be in a uniform circular motion is known as centripetal force means centre seeking force. This centripetal force is directly proportional to the square of the speed of the particle.
What happens when you apply force in an object in space?
It accelerates as long as the force is applied, and after that it continues at a uniform speed and direction.

a constant horizontal speed
If you exert a horizontal force of 600N to slide an object across the floor at a constant speed is the force of friction between the object and the floor greater than less than or equal to 600N?
Since the object is moving at a constant speed, the net force on it must be zero.If I'm applying a constant horizontal force, then the frictional force must be equal to my force = 600N and in the opposite direction to my force.

How fast is an object going if its speed and time graph is horizontal?
An object can only gain speed if there is a net force on it. If a net horizontal force acting on an object is large enough, or acts for a long enough time, the object can aquire a speed up to just under the speed of light, 3 x 10^8 m/s.
Why throwing a ball always put down in curve not in straight?
-- The only horizontal force on a thrown ball is the force of air resistance, so the horizontal acceleration is very small, and the horizontal speed stays almost constant. -- The vertical force on a thrown ball is the force of gravity, so the ball accelerates straight down at the acceleration of gravity. -- The result of unequal horizontal and vertical components of acceleration is a curved path.
Is there an angle for the plane at which no horizontal force can keep the mass moving at constant speed?
Sorry it is impossible to understand your question.
