Easy, to save energy
The advantage to using an incline plane (ramp) is that it reduces the amount of work.
Force required to move the object forward.
If we use a inclined plane to lift a object then the amount of energy used decreases applied force and wok
You use less force in moving it upwards as you are only subjected to a component of the weight (W sin angle).
applied force
Yes, it makes it easier to push the object up.
When a person is using an inclined plane it decreases the amount of force needed to move the object.
The 2nd class lever reduces the mass of an object, thus it reduces the amount of effort required to lift it. Eg: A wheelbarrow is a 2nd class lever, you are able to move a heavy object with it that you otherwise wouldn't be able to move by yourself.
An inclined plane allows an object to be lifted through a vertical distance using less force than is required to lift the object straight up. The shallower the angle of the inclined plane, the less force is required to raise the object. The inclined plane is a very simple machine that offers a mechanical advantage. Although the force needed to raise the object is reduced, the force needs to move through a longer distance. Therefore, it takes the same amount of energy to raise the object . In fact, as there is always an amount of friction, it will actually take more energy to lift that simply lifting it straight up. The most common example of an inclined plane is a ramp used to raise vehicles to a higher level.
It requires less force to move an object up an inclined plane if the slope is less steep.
It creates a mechanical advantage and reduces the force required to lift or move an object.
