An inclined plane is a surface that is not horizontal (level), with one end higher than the other. Pushing a broken down car is much easier and takes less effort downhill, than to push the same car uphill.
by increasing distance over which the force is applied
A simple machine. You know, inclined plane, lever, pulley, screw, wheel, or a wedge.
A force machine does not reduce the amount of work that has to be done
Because the force of gravity is no longer straight down on the object, it is at an angle. thus when you have a ramp some of the force due to gravity is dispersed in the x plane, causing the force down on the y plane (vertical) due to gravity ( mass x gravity) to be less thus decreasing the amount of force needed to lift.
When used appropriately, a pulley can be used to reduce the amount of force needed to move an object. By using multiple pulleys, one can change the direction that force needs to be applied to move an object, as well as reducing the amount of force that is necessary through mechanical advantage.

Reduce the friction
When a person is using an inclined plane it decreases the amount of force needed to move the object.
by increasing distance over which the force is applied
It requires less force to move an object up an inclined plane if the slope is less steep.
the less steep it is the less force you will need
A simple machine. You know, inclined plane, lever, pulley, screw, wheel, or a wedge.
the less force is needed.

By reducing friction [rolling instead of dragging across a surface]By decreasing the amount of force needed to perform an action (at the cost of reducing the amount of action) [levers, inclined plane]
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.
