What factors change the horizontal and vertical components of the weight of an object on a ramp?
The horizontal and vertical components don't change. In fact, weight is completely vertical, and has no horizontal component at all, regardless of what the object happens to be sitting on. But the components parallel to the ramp and normal to the ramp depend on the slope of the ramp.
How can you decrease the effort force needed to push a weight to the top of a ramp?
Lengthen the ramp, decrease the mass of the object, use a machine (e.g., a block and tackle) to pull the weight up the ramp, reduce the friction of the weight against the ramp, move the ramp further from the center of gravity of the earth, submerge the ramp in a liquid...tbere may be more ways but this should give you some ideas to consider.
How does weight effect speed down a ramp?
Yes, the weight of an object going down a ramp has an effect on its speed. Imagine a ramp . one with nothing in it , and a nothing with a person. a ramp or hill . and you give each a push at the same time which one will get down faster , the one with more weight because the force of the person on the front will make it faster. or you could do one at a time , and time each . either way the one with more weight is faster.
What energy would a cart have at the end of a ramp?
If it were released from the top of the ramp, the cart would have maximum kinetic energy at the bottom of the ramp since the gravitational energy at the top of the ramp is converted into the kinetic energy of the cart.
How would the input force needed to push a wheelchair up a ramp change if you increase the height of the ramp but not its lenght?
The effort needed would increase.

How does a ramp help to make work easier?
A ramp makes work easier by letting you elevate an object with less input force.

How can you measure sliding friction?
Since friction is a force, you need either a force meter or a ramp to measure it. It would be easier to measure with the force meter, but the ramp is more reliable. Method 1: Force meter. - attach a force meter to the object. - place the object on the horizontal surface you want to test. - pull the object horizontally until it moves. Keep pulling, while looking at the force meter. - the sliding friction is the average value of that force as you keep pulling. Method 2: Ramp - place your object on the ramp. the ramp should have as its surface the material you want to test. - raise 1 end of the ramp until the object begins to slide. this is the maximum angle you need. - Decrease the angle of elevation slightly. - place the object again on the ramp and nudge it. If it keeps moving, decrease the angle again. Repeat until the object is seen to stop after the nudge. - Use the equation friction = weight of the object in newtons x tangent of the angle. - repeat all steps and take an average value.

The effort needed would increase.
How does using a ramp make lifting a heavy object easier?
You get mechanical advantage by the slope of the ramp. You move the object horizontally and raise the object slowly as you do so.
Why do you think the amount of force needed to move the object changes the way it does base on the distance traveled on the on the ramp?
No. Unless the ramp reaches the sky, in which case, a change in the gravitational attraction should be considered. Or if you are considering a change in sliding friction based on a change in surface temperature, that could be a reason for the force to change.
How does a ramp make it easier to move heavy objects?
What a ramp does is trade distance for height. So it's not easier to move an object so much as it's easier to lift an object with a ramp.
What is an Egyptian ramp?
An Egyptian ramp is a ramp with a platform in the middle to reduce the incline of the ramp and/or to change the direction of incline.
How would the input force needed to push a wheelchair up a ramp change if you increase the height of the ramp but not its length?
The input force would increase as the height of the ramp increased. It wouldn't matter the distance. Ask me another one.
