An inclined plane is a sloped surface that makes it easier to move heavy objects by allowing them to roll or slide uphill with less force than lifting straight up. Inclined planes include wheelchair ramps, slides, and sloped roads. By increasing the length of an inclined plane, the angle of the slope decreases, reducing the amount of force needed to pull an object up since work done equals force times distance moved.

3. WHAT IS

6.  A sloping ramp up which heavy loads can be
raised by ropes or chains
OR
A plane inclined at an angle to the horizontal

7.  Ramps
 Sloping roads and hills
 Stairs

10.  An inclined plane is any slope or ramp, like a
wheelchair ramp or a slide. The ramp makes it
easier to lift something heavy, like a rock.
Instead of lifting the rock straight up, you can
push it a greater distance, but with less force.
The amount of work remains the same

11.  Work done = Force X Distance
W = F X S
If we increase the size of the inclined plane, that
reduces the angle of the ramp and force required
to pull the object will be less.
