4. TBQ - Inclined planes

 

 

Roads on hills are built to wind around in gentle slopes because they act like an pulleyinclined planeleverwedge. An inclined plane eliminates the need for forceincreases the speed automaticallyincreases the effort requiredreduces the effort required to move a vehicle to a higher level by increasing the height of the vehicledecreasing the distance travelledreducing the weight of the vehicleincreasing the distance travelled. Although the vehicle covers a longer path, it requires zero forcegreater forcehigher massless force to climb the hill. This makes driving harder to control vehiclesmore expensive to constructsafer and more convenientfaster but less stable, especially for heavy vehicles, and increases the weight of vehiclesreduces the chances of vehicles slipping or losing controlincreases the chances of skiddingmakes vehicles move without friction on steep slopes.
