The advantage of using an iclined plane to lift an object is that it reduces the amount of?
If we use a inclined plane to lift a object then the amount of energy used decreases applied force and wok
What to you use to measure the amount of force needed to pull something?
You can use the force gravity to measure the amount of force, because gravity makes an object tied to a string hang.
Does a pulley use less force?
There are a variety of different designs for pulleys, depending upon what you need to do with them. A pulley can be used to change the direction of a force without changing the amount of force that you apply, but there are also pulleys that do reduce the amount of force you have to use to lift something.
Why it is easier to pull an object then to push it?
Actually, its not. It depends on the direction of the force vector use to push or pull. If the two directions are equal, and the position of the force vectors are consistent with each other, then the amount of force to push would be the same as the amount of force to pull. You are probably realizing by now that when you pull an object, there is a tendency to lift it up from the surface, reducing friction, while when you push an object, the tendency is to push it down on the surface, increasing friction. This is why you have to be very careful and consistent in how you measure things.
Why do you have to use force to lift objects?
Because there is a force of gravity constantly pulling it towards the center of earth. When you exert enough force to over come the gravity acting on an object it is lifted
The amount of force that you must use on an object to lift it is?
Any force greater than its weight.
The advantage of using an iclined plane to lift an object is that it reduces the amount of?
If we use a inclined plane to lift a object then the amount of energy used decreases applied force and wok
Does the use of an incline plane reduce the force necessary to lift up an object?
Yes. It is easier to push an object up a plane than lift it straight up. It does not reduce the total amount of energy needed to lift it up.
What advantage of using inclined plane to lift an object is that it reduces the amount of what?
You use less force in moving it upwards as you are only subjected to a component of the weight (W sin angle).
What to you use to measure the amount of force needed to pull something?
You can use the force gravity to measure the amount of force, because gravity makes an object tied to a string hang.
What formula do you use determine the amount of work done on an object?
force times dictance

How do you use body force on roblox?
Body force objects are used by putting them in a brick, and setting their force value to the amount of force you want to apply on that object. The object will then have a constant force applied to it in the direction and speed that you specified.
How buoyancy force works?
its use formula : Fa = density . gravitation . high because water can lift up an object so if an object dipped in water', mass of an object will decrease
Why do you have to use force to lift objects?
Because there is a force of gravity constantly pulling it towards the center of earth. When you exert enough force to over come the gravity acting on an object it is lifted
How is the work output of a machine related to its work input?
Note: This answer addresses simple machines, such as levers, pulleys, and ramps - it does not address complex machines, such as engines..Machines affect work by applying one or more of the following principles:altering the amount of force applied in order to do the work;altering the amount of time over which the force is applied; and/oraltering the direction that the force is applied..A simple pulley, or a balanced lever, does not change the amount of force required to lift an object, or the time during which the force is applied, but they do change the direction of the force. A balanced lever (a teeter totter) makes it easier to lift another object (your friend on the other end of the teeter totter) because you can use your own weight to help lift that object (your friend). Such simple, balanced machines do not decrease the force, nor increase the amount of time during which the force is applied - they merely redirect the force, which is often helpful..Ramps, pulleys, and levers can also reduce the required force, in addition to changing the direction of the applied force, making the work easier in two ways. For example, a compound pulley reduces the amount of force required to lift a heavy object, but it now takes more time of that applied force to lift the weight. When this occurs, the machine does not actually change the amount of work done, but the machine makes it easier to do the same amount of work by spreading that work done over a longer period of time at a reduced force..Some machines use the opposite principle - they require more force than normal, but the force is applied over a reduced period of time. A catapult is an example of this principle - it is a lever in which more work is required to lift an object than without the catapult lever, but the object is lifted so quickly that, by the time the object is lifted, it is travelling fast enough to become a ballistic object.A machine affects work done by magnifying human's physical capabilities which reduces the intensity of the work.
