Inclined Planes
Simple Machines: Inclined Planes
Question | Answer |
---|---|
ramp | spreads force over a longer distance |
inclined plane | a flat, sloping surface over which objects may be rolled or slid to a higher level |
wedge | two inclined plane wrapped around a central point or a winding inclined plane |
friction | force that resists motion |
screw or bolt | an inclined plane wrapped around a central point or a winding inclined plane |
an inclined plane is a___ ___that reduces the force required to move an object over a vertical distance or height | simple machine |
friction is an important consideration in sliding or rolling an object up a___or inclined plane | ramp |
the resistance force is in the direction of___, and the resistance motion is in the opposite direction | gravity |
like the ramp, the___spreads the force needed to move the load over a longer distance | wedge |
the wood screw and drill bit are__ __because the threads are inclined planes, but there is a wedge on the points | compound machines |
