A wheel, together with an axle overcomes friction by facilitating motion by rolling. In order for wheels to rotate,
a moment needs to be applied to the wheel about its axis, either by way of gravity,
or by application of another external force

6. Calculations Force 0.2 x 9.8 = 1.96 N Work 1.96 x 0.4867 = 0.953932
(Mass of an object) x 9.8
0.2 x 9.8 = 1.96 N
