Want this question answered?
an inclined plane! atleast that's what I think
It requires less force to move an object up an inclined plane if the slope is less steep.
If the surface is sticky the energy needed to break the "sticky" ionic bonds will not be able to contribute to the motion of the object rolling down the inclined surface.
the less steep it is the less force you will need
The main function of an inclined plane is to decrease the work needed to push an object at an angle uphill.
As an inclined plane gets shorter, the angle gets steeper and the effort becomes greater.
More effort, since the angle will need to be increased.
by increasing effort distance hence reducing the effort needed to work

The effort required is directly proportional to the sine of the angle of inclination.Since the sine of an angle increases with increase in angle, therefore the effort required also increases.

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.
they were needed
