When you run up the stairs you do more work than when you walk up slowly?
In other words, it is a measurement of how fast you are using energy. Whether you run up a flight of stairs in 5 seconds or take a slow walk up the same flight in 40 seconds, you are doing the same amount of work. However, you are doing it at a different rate. When you run up the stairs you are working much faster.
Is it better to run or walk up the stairs?
When you stair climb, you burn twice the fat in half the time than if you run and three times more than walking. An intense stair-climbing exercise session will produce more aerobic benefits in a shorter amount of time than running or walking. One hour of stair climbing will burn approximately 1,000 calories.
Which requires more power walking or running up the stairs Why?
More energy is needed to do work faster (i.e. more power). Walking up the stairs is the same amount of WORK as running up the stairs. The rate at which work is done determines the amount of power that is generated while doing the work. Going faster uses up the same amount of energy; it just uses it up faster.
How much power does it take to go up the stairs?
The average stair lift draws about 250 watts. This is in line with what’s expected, simply because stair lifts don’t have to accelerate hard, and the force required to lift a 220-pound human 10 feet in the air is about 3 kilojoules. Wattage is simply a measure of the number of joules consumed per second.
How many watts does it take to run up the stairs?
For example, if the stairway is 5 meters high, you weigh 75 kilograms and you walk up the stairs in six seconds, you would multiply 75 by 9.81,which yields 735.75, and then multiply the result by five, for a total of 3,678.75. Divide that result by six, for a total power output of 613 watts.
What is the relationship between work and distance?
It is directly related to both the force applied to the object and the distance the object moves. Work can be calculated with this equation: Work = Force x Distance.
What kind of relationship is between work and distance?
Displacement is the distance and direction an object is moved. Force and work are directly proportional to each other, while force and displacement are indirectly propotional.
Why is force proportional to acceleration?
As we increase the force on an object the acceleration increases proportionally. Since the mass does not change as the acceleration increases, we can say that force is equal to acceleration. Force is directly proportional to acceleration (force ~ acceleration)
