As common sense would suggest, it is easier for them to lift light objects.
Pulleys exist on wells to make it easier to remove the bucket. Once the bucket has gone down to the water, it is heavy and hard to lift straight up. So the pulley allows the person to pull down and/or at an angle to make the lifting easier. A block and tackle (a network of pulleys) could be used here to make the lifting even easier.
a pulley is a simple machine made of a wheel on an axle. It makes lifting easier
To make the job easier for you and can help you with the heavy lifting.
What a ramp does is trade distance for height. So it's not easier to move an object so much as it's easier to lift an object with a ramp.
Bearing principle is very simple: objects rolling easier than slide.
The pulley makes work of lifting easier then lifting by hand.
As common sense would suggest, it is easier for them to lift light objects.
He invented the Lifting screw -which lifts water up to a higher level, pulley-which makes lifting heavy objects much easier, Golden Crown, as well as the Catapult,the Burning mirror and the lever The arkamedes screw... 1gameboyc's comment, Wrong! I study Archimedes and he did not invent the lever. The lifting screw is known as the Archimedes screw.. it was invented in the 3rd century
Not easier because of the quantity or mass of feathers are larger than 40 lbs of lead
Both, and neither. Both, because levers successfully assist people in lifting heavy objects (which requires force) and opening things (which requires force). Neither, because the definition of a lever has nothing to do with how the theory is used.
because they are smaller than larger objects
to counterbalance the weight of the water bucket and make for easier lifting
Because it made work easier, especially lifting.
a lever makes work easier in the sense that it help carry a heavy load from the ground in a process called lifting!
I don' t know
Grouping objects is an important organizational skill. You should group like objects to keep things orderly and easier to find or understand.
