What is the differences between lift and escalator?
a lift goes vertical. an escalator is moving stairs.
Which of these is true of a person walking up the steps of a downward-moving escalator a a constant speed?
Here are some things that are true:* The combined speed is also constant * To get the combined speed, you need to subtract one speed from the other (the speed of the escalator, and the speed of the person relative to the escalator) * Acceleration is zero
What is relative physics?
Relative means it depends on the person's reference frame/point-of-view. For example, when you're in a moving car, your point-of-view tells you that the car is not moving at all (after all you're inside the car all the time, you only know the car is moving because the objects outside the car are moving against you). But another person standing on the sidewalk will see your moving car as moving at, say, 50 mph.
How do you know when an object is moving?
Change of position relative to another object
If you are standing in an elevator that is moving up at a steady speed of 1 meter per second what is your motion relative to the elevator?
None. 0 mps.
What is another for a moving staircase?

What is another name a moving staircase?
Another word for a moving staircase is 'escalator'?
What is another answers for a moving staircase?
An escalator.
How fast are you moving relative to the earth when you are standing still?
"Standing still" IS a measurement relative to the Earth. Relative toother things, you are moving with high speeds in complicated paths.But relative to the Earth, you are standing still.
What do you call a moving walkway that goes up or down hill but does not have steps?
Another word for a moving staircase is 'escalator'?

How would you calculate the resultant velocity of two velocities in opposite direction what direction is the larger velocity?
Vector addition of velocities would be if something like you were on an escalator, which is going down, and you tried to run up the escalator. So if the escalator is moving down at a rate of 5 ft/sec and you run up at 13 ft/sec (relative to the escalator) then the net velocity relative to the Earth is 8 ft/sec up. So you just subtract, because the two vectors are in the same line. OK so really the direction is at an angle (rather than 'up'). The larger velocity direction will determine the net direction. If you were walking up the escalator at 3 ft/sec (relative to the escalator), then your net velocity is 2 ft/sec down.
