What is something that can split an object apart?
A wedge is a simple machine used to push two objects apart. A wedge is made up of two inclined planes. These planes meet and form a sharp edge. This edge can split things apart.
What is something that reduces the friction of moving something?
Wheel
Wheel and axle The wheel greatly reduces the friction encountered when an object is moved over a surface.
Is wheel a simple machine?
The wheel and axle is a type of simple machine used to make tasks easier in terms of manipulating force by applying the concept of mechanical advantage. The wheel and axle consists of a round disk, known as a wheel, with a rod through the centre of it, known as the axle. The wheel and axle both rotate at the same rate.

Is made of a wheel attached to a rod?
A wheel and axle is a simple machine made of a rod attached to the center of a wheel. A wheel and axle is a special kind of lever that moves or turns objects.
Why do rollers reduce friction?
Rollers: The Solution By breaking the gravitational bond between two surfaces (by being placed between the objects), rollers reduce friction—allowing seemingly unmovable objects to easily be moved from one point to another. Rollers are basically a variation of the wheel.
Is a wheel a tool or a machine?
It’s a simple machine, just like a lever, that allows a small effort over a greater distance do the same work as a larger effort over a smaller distance.
Is doorknob a wheel and axle?
A door knob or door handle is used to open or close the door easily. A wheel and axle is a simple machine in which the axle attaches the object to the wheel. A door knob has an axle in the middle with a wheel. Therefore, a doorknob is an example of a simple machine and not a screw.
