because the long ramp decreases the force you need to lift an object, but increases the distance you must move the object
Physically pushing against a wall can be considered as doing work in a physics context, as work is defined as the force applied over a distance. The force you exert on the wall does not result in any displacement of the wall, but work is still being done in the physics sense, as long as the force is being applied.
You would need to push with less force on a longer inclined plane compared to a regular sized inclined plane to move the box up the slope. This is because the longer incline reduces the steepness of the slope, which decreases the amount of force required to counteract gravity.
Yes, a pulley make work easier by changing the direction of the force needed to lift an object. It allows you to pull downward on the rope instead of lifting upwards, which can reduce the amount of effort required to lift the object.
Depends on the job at hand. The most common use is to multiply force so you can move something that weighs more than you can lift on your own. In doing this you give up distance. Place the lever and fulcrum so that the fulcrum is close to the 'load'. When you push on the long end of the lever it moves a long distance with a small effort, The load will be lifted a shorter distance.
Incorrect lifting can cause problems by straining the muscles and ligaments, leading to injuries such as sprains and strains. It can also put excessive stress on the spine, leading to back pain and potential long-term damage to the vertebral discs.
well I've been lifting and my friend pushups and well i totally beat him as far as muscels. PS depends what your lifting and for how long
There's no set answer, it depends on how long and how hard you work out. Pushing hard, maybe 450 cals/hour.
The amount of calories burned lifting 5 pound weights varies depending on different factors. Gender, current weight, age, and the amount of time you spend lifting the weights are factors that need to be considered before determining the amount of calories it burns.
Can? It might be possible but it's unlikely. Back problems are related to lifting.
It depends on a number of personal factors, but a beginner should begin to see definite results from an effective weight-lifting routine in around four weeks.
The amount of energy that is used when playing sports depends on which sport and how long you are doing the activity.

Anything over a month is pushing it.

If you are just lifting regular weights (like barbells), then the brand of the weight does not matter as long as the amount of weight is the same. If you are using a machine, it could matter because the angle you lift at can be different.
Depends on what you are doing and how hard you are exercising. I have a running watch that estimates calorie burn and it typically tells me about 100 calories per mile. So a 15 mile run would do it for you.
