When you are sprinting with a suitcase when is work being done on your suitcase?
Technically, no; work is performed when lifting the suitcase, but not when holding it level. Work IS performed to accelerate the suitcase at the beginning of the sprint, when turning or climbing stairs, and to slow it down at the end; but carrying the suitcase at a constant velocity and constant height is not "work".
Is walking is the work against gravity?
Walking across the room is not work against gravity.Walking up the stairs is work against gravity.Walking down the stairs is work with gravity.
How much work is done when a 70kg person climbs a ladder meters tall?
At least 3,500 joules, if his climbing effort is 100% efficient, but probably more than that.
Does an inclined plane make work harder?
No, it makes work easier at the expense of more work. Climbing stairs can be done faster than climbing a ramp, but climbing the ramp is easier, since it is less work over a longer time.
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.

How elevator helps people to make work easier?
it helps us by not climbing up the stairs. and if we are in a hurry we can just ride the elevator. and how about if we brought heavy and fragile things?, we cannot carry them using the stairs, using the escalator so we use the elevator that is why most of the malls are using elevators just like SM, Mall of Asia and Ayala that can be found in the Philippines.

How does a ladder work?
Ladders work similarly to climbing stairs. It is also somewhat similar to climbing a ramp, except that the steps force you to walk a predetermined distance with each movement. So you get to climb a small bit at a time rather than climb a distance that is too far and which you cannot reach.
Does climbing stairs for exercise affect the knees of old women?
Climbing stairs is a very good work out! If you do not have very strong knee joints, I would suggest taking something like cod liver oil. This is very good for keeping strong healthy joints. Keep climbing stairs, and the more you do, the easier they will become. (Try not to over-do it though!) =) Alex, 17. Older people should get an evaluation from their physician and fitness trainer to make sure that they are ready to take up stair climbing as an exercise. This is particularly important for people who have been sedentary or have had injuries previously. Start with short sessions of stair climbing and gradually increase the duration and intensity as the muscles and joints get more conditioned. -Eliza8

Why do you feel more tired when you climb up stairs?
Whether you walk or run you are still lifting the mass of your body through the same height against gravity, so the amount of work done is equal in each case, but where the work is done in less time more power is required. Yes, you exert more power when you run up the stairs.
