How does the weight of a backpack affect how fast you can go?

another important concept apart from weight is the centre of gravity (CG), a point where all your mass can be assumed to be concentrated. apart from the obvious statement that the heavier you are, the harder it is to run, if you are carrying a heavy backpack, this would shift your CG backwards, an antithesis to the fundamental of running forward. in plain words, seen those athletes in the olympics? they bend forward to propel themselves faster in the forward direction. therefore, theoretically speaking, you shud be able to run (albeit marginally) faster with a "front"pack than a backpack of equal weight!

Need more information. In general, the answer is that the dynamic load depends on how quickly the payload decelerates. The dynamic load will be the mass of the payload times the peak deceleration rate. In a strength calculation, do not forget to include the static weight component of the load.\n\nThe deceleration depends on the elasticity of the cables supporting the load.\nIf the crane has a flexible supporting structure, then that could also affect the result. (You didn't say whether the "crane" is the traveling overhead hoist type usually seen in a factory - which typically has a stiff support - or the cantilevered truss type seen on construction sites - where the support might have a little flexibility.)

It is different for every different circumstance. The key is when the force of gravity pulling you down is exactly equal to the drag on you from the rushing air, you arrive at terminal velocity. If you have a lot of drag (parachute deployed, a lot of loose clothing), it happens pretty quick. If you have low drag (tights, bald) then it takes longer.

It depends on how far its going and how much it weighs.

Force = mass x acceleration\n Mass = weight times gravity\nAcceleration is speed/time\n example if I’m playing football and I want to move the other player assuming we are both on the same planet (gravity is constant) and we are both moving at the same speed at each other I can do so if am heavier than him (increase wt (g) = increase mass) or I decease the time it takes to reach that player (constant speed and distance in less time = acceleration) or I can do both. This is how you increase force by increasing acceleration, mass, or both

It depends on windspeed and direction, and the planes direction in relavence to that speed and direction. It depends on the speed of the plane. It depends on the density of the object, because of wind resistance. EX. feather would be close, lead ball would be further. Your question is like me saying, "I am in a car, how long will it take me to get to McDonalds?" Not enough info

it depends how fast u go. lol

Objects of different mass do fall at the same speed, but air resistance hinders this fact.  For example, if you drop a bowling ball and a feather at the same time on the Earth, obviously the bowling ball falls faster. \n\nHowever, on the moon, when the astronauts dropped a feather and a bowling ball, they hit the ground at the same time. \n\nIt would seem that the bowling ball should fall faster since gravity is pulling on it with more force. But, with the more mass, comes more inertia, which meas it resists being pulled more than the feather. So, the feather is pulled less, but it resists less as well, so because of that, they will fall at the same time. The relationship between the force of pull and the object's inertial compensates exactly so that all objects fall at the same rate.

A. height and weight. Potential energy is the energy contained in an object due to its position in a force field (such as a gravitational field), and has nothing to do with speed (which would be kinetic energy). Thus you can eliminate options C and D. Further, energy is defined as the ability to do work, and work is simply force*distance. Since the weight of an object would be applied over a greater distance if the object fell from higher up than if it fell from a lower distance, height does influence potential energy, which means the only remaining option is A.\n\nBTW, about B - it might seem that potential energy also depends on mass since that will affect the weight of the object, but if you changed the mass of an object without changing its weight (by varying the gravity in inverse proportion to the mass), the potential energy would not change. Conversely, there's no way to change either the object's height or weight while holding the other constant without changing its potential energy, which is why A is right and B is wrong.

As a previous answer stated, different woods (and even different pieces of the same type of wood) have different densities and thus different weights and may affect speed accordingly.  But if your underlying question is about the impact of materials on speed, your selection of wood is minimal compared to other factors.  Since there is a maximum weight allowed for cars your choice of wood would not materially affect your car's speed as much as just buying the regular pinewood kit and using lead stick-on weights to reach the maximum weight (which would also give you the flexibility to place the weight where you wanted it - front, back, center, etc.).  \n\nOne factor that has a far greater impact on overall performance is making sure the axles are square to the body of your car, because, to paraphrase Jonnie Cochran, if your wheels ain't square, you ain't going nowhere.  If your axles are perfectly square to the car body your wheels will turn smoothly and not slow your car down by jumping up and down or wiggling back and forth across your lane.\n\nAnother important facter is the "freeness of spin" of your wheels.  You can sand the axles and use graphite power for reduced friction.  \n\nI'm not sure if this is exactly what you're looking for, but in the grand scheme of things, wood type does not have a great impact on car speed.

It used to be that being a caddy meant having to heft those great big tour bags around. Usually they had the 14 clubs, an umbrella, extra shoes and socks, balls, and other things like snacks and whatnot. The bag itself weighed 10 to 15 pounds, so it could be quite a struggle when you added everything into it. Also, those bags had one strap that you looped over one shoulder.\n\nThings are easier now thanks to the double straps, which evenly distribute the weight of the bag and make it easier to carry, especially over extended distances. It also took the height issue out of the equation, because the one end that used to hang down is now more on a 45 degree angle.\n\nStrength shouldn't be too much of a concern, but you need to be in decent shape for walking around with that extra weight on your back. Just remember to lean forward slightly when walking to avoid excess strain on your lower back, and you should be fine.\n\nHappy looping!

It's not a matter of distance, it's a matter of terrain and habitat.  I can hike a great deal farther with weight on my back in the Northeast US than I can in the desert.  \n\nYou have to consider where you will be carrying that backpack.  My largest backpack is custom designed.  If I choose to bend down and get a sip from a creek or tie my shoe, I can do it without losing my balance.\n\nI can go for long distances and not feel the weight on my shoulders, because I have appropriate padding and support straps.\n\nIf you are planning the trip near to where you live, pack your gear and get out there until you cannot continue.  Note what's bothering you, rest, then fix what you can on site - maybe you need to repack your gear.  Maybe you need padding in one shoe.  Maybe you need to adjust your trekking poles.  \n\nWhen you get back home, address the issues you could not fix on the trail.  Maybe you need to leave some gear behind.  \n\nMaybe you need to add something different.   When I do desert hikes - I carry a hydration water bladder with a tube, so I can sip water as needed.  I don't carry this when I'm not in the desert, unless it's an incredibly hot day.\n\nAnother consideration - are you going alone or with a group?  Are you deciding when to begin and end your hike?  If it's summertime - do yourself a favor hike from first light until sun up.  Try not to exert in the heat of the day and hike from just before sunset until dark.  \n\nHappy Trails.

It wont make things load slow, they arent stored in memory, they are cached on disk. But you can also use them to track where you have been going and what you have been doing too. If you dont have the size maxed out, you can eat a lot of hard drive space too.

The faster an object (in this case your arm) is moving, the more mass in the direction it's travelling it has.\n\nYou have to overcome the inertia (tendancy to stay in place in this case) holding the paper sheets to each other.  If you pull the roll slowly the paper doesn't tear and instead pulls out more paper; however, if you snap it quick the paper'll break off for you.  In other words: you produce more inertia in another direction than the paper can resist.\n\nA martial artist puts lots of power behind the motion, therefore building up enough inertia to break the board.  Olympic weightlifters do it too: rather than moving slowly to lift the weight and therefore wasting energy, they instead lift it as quickly as possible, putting all the energy they can into the lift.

it can either increase the speed of the fall by reducing the air resistance or decrease it by creating more air resistance. think parachute and missle.

Gravity, makes your neck go baggy! It drags a lot of things earthbound, especially when you hit 50!

when you travel faster than the speed of sound.
