Horizontal motion doesn't require any force.
Horizontal work = (force) x (distance) = 0.

What is the differences between lift and escalator?
a lift goes vertical. an escalator is moving stairs.
Is there some limit to the height of the flight of stairs used and the horsepower developed?
There's no limit to the height of the stairs, but because power is the rate of doing work, different people would run up several flights of stairs at different rates, since each person has a "limit" on the amount of power she/she can produce.
Vertical connectors between floors of a building are known as?
Vertical connectors.. hmm do you mean the support structure? In that case it might be pillars; however, stairs and elevators also connect floors if you think about it.
What is the word that describes an up and down motion?
The word that describes an up and down motion is vertical. Stairs are considered vertical, even though they are usually set at an angle. Horizontal would mean a side to side motion.
What is the average power supplied by a 60.0 kg person running up a flight of stairs a vertical distance of 4.0 m in 4.2 s?
Calculate how much his potential energy increases in one second. Use the formula PE = mgh (mass x gravity x height), mass in kg, gravity = 9.8 (meters per second squared), convert height to meters. Result will be in Joules. The standard unit of power, Watts, means Joules / second.
What is rise of stair?
The rise of a stair is the vertical distance between the treads. The term can be used for the height of the full set of stairs. A riser is the vertical board running along the front of the step.
How do you find the slope of stairs?
Rise divided by run. That is, the height of the stairs divided by how much they measure across (horizontally).
What is the differences between lift and escalator?
a lift goes vertical. an escalator is moving stairs.
Explain how potential difference in a battery is similar to a staircase?
The potential difference in a battery is like the height of the stairs. The amount of charge separated in a battery is like the mass moved up the stairs. The potential energy in the battery is due to both the potential difference (volts) and the amount of charge that has been separated (coulombs).
When you climb stairs do you do any work?
Yes. You perform the work of lifting your body weight a distance equivalent to the height of the stairs. This is why some older or overweight people get out of breath when climbing stairs.
What is the vertical line that spilts up group 12 and 13 in the periodic table?
The elements on the line (stairs) are metalloids. The elements to the left of the stairs are metals and those to the right are non-metals.
What does the word x-coordinate mean?
As my old scout leader used to say, along the corridor then up the stairs. x = the corridor or horizontal axis y = stairs or the vertical axis

Why do stairs appear the same level to me?
people measure the average height of people. there is probably an average one step stair height.
Is the side view of stairs a polygon?
Yes, but with a few conditions:You must include the horizontal line along the bottom and the vertical line from the bottom to the top stair;The noses of the stairs must not be rounded.
How do you measure a staircase?
For height measure only the up bits (side of the stairs) and add them together, for along measure the top faces of the stairs and add them together.
